Find the Quadratic Equation (2,11.75)

$(2, 11.75)$

Step 1

$x = 2$ and $x = 11.75$ are the two real distinct solutions for the quadratic equation, which means that $x - 2$ and $x - 11.75$ are the factors of the quadratic equation.

$(x - 2) (x - 11.75) = 0$

Step 2

Expand $(x - 2) (x - 11.75)$ using the FOIL Method.

Apply the distributive property.

$x (x - 11.75) - 2 (x - 11.75) = 0$

Apply the distributive property.

$x \cdot x + x \cdot - 11.75 - 2 (x - 11.75) = 0$

Apply the distributive property.

$x \cdot x + x \cdot - 11.75 - 2 x - 2 \cdot - 11.75 = 0$

Step 3

Simplify and combine like terms.

Simplify each term.

Multiply $x$ by $x$ .

$x^{2} + x \cdot - 11.75 - 2 x - 2 \cdot - 11.75 = 0$

Move $- 11.75$ to the left of $x$ .

$x^{2} - 11.75 \cdot x - 2 x - 2 \cdot - 11.75 = 0$

Multiply $- 2$ by $- 11.75$ .

$x^{2} - 11.75 x - 2 x + 23.5 = 0$

Subtract $2 x$ from $- 11.75 x$ .

$x^{2} - 13.75 x + 23.5 = 0$

Step 4

The standard quadratic equation using the given set of solutions ${2, 11.75}$ is $y = x^{2} - 13.75 x + 23.5$ .

$y = x^{2} - 13.75 x + 23.5$

Step 5

Find the Quadratic Equation (2,11.75)
