Introduction

The Master Product method is a technique used to solve quadratic equations of the form $ax^2 + bx + c = 0$ . This method involves using a specific product, known as the Master Product, to simplify the equation and find its solutions. In this article, we will use the Master Product method to solve the quadratic equation $6x^2 - 13x - 8 = 0$ .

The Master Product Method

The Master Product method is based on the concept of factoring a quadratic expression into two binomial factors. The Master Product is a specific product that is used to simplify the quadratic equation and make it easier to factor. The Master Product is given by the formula:

M = ac - b^2

where $a$ , $b$ , and $c$ are the coefficients of the quadratic equation.

Finding the Master Product

To find the Master Product, we need to substitute the values of $a$ , $b$ , and $c$ into the formula. In this case, we have:

a = 6, b = -13, c = -8

Substituting these values into the formula, we get:

M = (6)(-8) - (-13)^2

Simplifying this expression, we get:

M = -48 - 169

M = -217

However, we are given that the Master Product is -48. Therefore, we will use this value in our calculations.

Solving the Quadratic Equation

Now that we have the Master Product, we can use it to solve the quadratic equation. The Master Product method involves finding two numbers whose product is equal to the Master Product and whose sum is equal to the coefficient of the linear term. In this case, we need to find two numbers whose product is equal to -48 and whose sum is equal to -13.

Factoring the Quadratic Expression

To factor the quadratic expression, we need to find two binomial factors whose product is equal to the quadratic expression. We can do this by using the Master Product method.

Let's assume that the quadratic expression can be factored as:

(6x + p)(x + q) = 6x^2 - 13x - 8

where $p$ and $q$ are constants.

Expanding the left-hand side of this equation, we get:

6x^2 + (p + 6q)x + pq = 6x^2 - 13x - 8

Equating the coefficients of the linear term, we get:

p + 6q = -13

Equating the constant terms, we get:

pq = -48

Solving for p and q

We can solve for $p$ and $q$ by using the fact that their product is equal to -48. We can write:

p = \frac{-48}{q}

Substituting this expression into the equation $p + 6q = -13$ , we get:

\frac{-48}{q} + 6q = -13

Multiplying both sides of this equation by $q$ , we get:

-48 + 6q^2 = -13q

Rearranging this equation, we get:

6q^2 + 13q - 48 = 0

Solving the Quadratic Equation

We can solve this quadratic equation by factoring or using the quadratic formula. Let's use the quadratic formula:

q = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

where $a = 6$ , $b = 13$ , and $c = -48$ .

Substituting these values into the formula, we get:

q = \frac{-13 \pm \sqrt{13^2 - 4(6)(-48)}}{2(6)}

Simplifying this expression, we get:

q = \frac{-13 \pm \sqrt{169 + 1152}}{12}

q = \frac{-13 \pm \sqrt{1321}}{12}

q = \frac{-13 \pm 36.5}{12}

Finding the Values of p and q

We can find the values of $p$ and $q$ by substituting the values of $q$ into the equation $p = \frac{-48}{q}$ .

Let's assume that $q = \frac{-13 + 36.5}{12} = 2.042$ . Then:

p = \frac{-48}{2.042} = -23.5

Let's assume that $q = \frac{-13 - 36.5}{12} = -4.542$ . Then:

p = \frac{-48}{-4.542} = 10.6

Factoring the Quadratic Expression

Now that we have the values of $p$ and $q$ , we can factor the quadratic expression:

(6x + p)(x + q) = (6x - 23.5)(x + 2.042)

(6x + p)(x + q) = (6x - 23.5)(x - 4.542)

Solving for x

We can solve for $x$ by setting each factor equal to zero and solving for $x$ .

Let's solve the equation $(6x - 23.5) = 0$ :

6x - 23.5 = 0

6x = 23.5

x = \frac{23.5}{6}

x = 3.917

Let's solve the equation $(x + 2.042) = 0$ :

x + 2.042 = 0

x = -2.042

Let's solve the equation $(6x - 23.5) = 0$ :

6x - 23.5 = 0

6x = 23.5

x = \frac{23.5}{6}

x = 3.917

Let's solve the equation $(x - 4.542) = 0$ :

x - 4.542 = 0

x = 4.542

Conclusion

In this article, we used the Master Product method to solve the quadratic equation $6x^2 - 13x - 8 = 0$ . We found the Master Product to be -48 and used it to factor the quadratic expression. We then solved for $x$ by setting each factor equal to zero and solving for $x$ . We found two solutions for $x$ : $x = 3.917$ and $x = -2.042$ .
