Find the Quadratic Equation 10 , -7

$10$ , $- 7$

Step 1

$x = 10$ and $x = - 7$ are the two real distinct solutions for the quadratic equation, which means that $x - 10$ and $x + 7$ are the factors of the quadratic equation.

$(x - 10) (x + 7) = 0$

Step 2

Expand $(x - 10) (x + 7)$ using the FOIL Method.

Apply the distributive property.

$x (x + 7) - 10 (x + 7) = 0$

Apply the distributive property.

$x \cdot x + x \cdot 7 - 10 (x + 7) = 0$

Apply the distributive property.

$x \cdot x + x \cdot 7 - 10 x - 10 \cdot 7 = 0$

Step 3

Simplify and combine like terms.

Simplify each term.

Multiply $x$ by $x$ .

$x^{2} + x \cdot 7 - 10 x - 10 \cdot 7 = 0$

Move $7$ to the left of $x$ .

$x^{2} + 7 \cdot x - 10 x - 10 \cdot 7 = 0$

Multiply $- 10$ by $7$ .

$x^{2} + 7 x - 10 x - 70 = 0$

Subtract $10 x$ from $7 x$ .

$x^{2} - 3 x - 70 = 0$

Step 4

The standard quadratic equation using the given set of solutions ${10, - 7}$ is $y = x^{2} - 3 x - 70$ .

$y = x^{2} - 3 x - 70$

Step 5

Find the Quadratic Equation 10 , -7
