Find the Quadratic Equation (8,-6)

$(8, - 6)$

Step 1

$x = 8$ and $x = - 6$ are the two real distinct solutions for the quadratic equation, which means that $x - 8$ and $x + 6$ are the factors of the quadratic equation.

$(x - 8) (x + 6) = 0$

Step 2

Expand $(x - 8) (x + 6)$ using the FOIL Method.

Apply the distributive property.

$x (x + 6) - 8 (x + 6) = 0$

Apply the distributive property.

$x \cdot x + x \cdot 6 - 8 (x + 6) = 0$

Apply the distributive property.

$x \cdot x + x \cdot 6 - 8 x - 8 \cdot 6 = 0$

Step 3

Simplify and combine like terms.

Simplify each term.

Multiply $x$ by $x$ .

$x^{2} + x \cdot 6 - 8 x - 8 \cdot 6 = 0$

Move $6$ to the left of $x$ .

$x^{2} + 6 \cdot x - 8 x - 8 \cdot 6 = 0$

Multiply $- 8$ by $6$ .

$x^{2} + 6 x - 8 x - 48 = 0$

Subtract $8 x$ from $6 x$ .

$x^{2} - 2 x - 48 = 0$

Step 4

The standard quadratic equation using the given set of solutions ${8, - 6}$ is $y = x^{2} - 2 x - 48$ .

$y = x^{2} - 2 x - 48$

Step 5

Find the Quadratic Equation (8,-6)
