Find the Quadratic Equation (4,3)

$(4, 3)$

Step 1

$x = 4$ and $x = 3$ are the two real distinct solutions for the quadratic equation, which means that $x - 4$ and $x - 3$ are the factors of the quadratic equation.

$(x - 4) (x - 3) = 0$

Step 2

Expand $(x - 4) (x - 3)$ using the FOIL Method.

Apply the distributive property.

$x (x - 3) - 4 (x - 3) = 0$

Apply the distributive property.

$x \cdot x + x \cdot - 3 - 4 (x - 3) = 0$

Apply the distributive property.

$x \cdot x + x \cdot - 3 - 4 x - 4 \cdot - 3 = 0$

Step 3

Simplify and combine like terms.

Simplify each term.

Multiply $x$ by $x$ .

$x^{2} + x \cdot - 3 - 4 x - 4 \cdot - 3 = 0$

Move $- 3$ to the left of $x$ .

$x^{2} - 3 \cdot x - 4 x - 4 \cdot - 3 = 0$

Multiply $- 4$ by $- 3$ .

$x^{2} - 3 x - 4 x + 12 = 0$

Subtract $4 x$ from $- 3 x$ .

$x^{2} - 7 x + 12 = 0$

Step 4

The standard quadratic equation using the given set of solutions ${4, 3}$ is $y = x^{2} - 7 x + 12$ .

$y = x^{2} - 7 x + 12$

Step 5
