Examples

$(1, 5)$

Step 1

$x = 1$ and

$x = 5$ are the two real distinct solutions for the quadratic equation, which means that

$x - 1$ and

$x - 5$ are the factors of the quadratic equation.

$(x - 1) (x - 5) = 0$

Step 2

Expand

$(x - 1) (x - 5)$ using the FOIL Method.

Step 2.1

Apply the distributive property.

$x (x - 5) - 1 (x - 5) = 0$

Step 2.2

Apply the distributive property.

$x \cdot x + x \cdot - 5 - 1 (x - 5) = 0$

Step 2.3

Apply the distributive property.

$x \cdot x + x \cdot - 5 - 1 x - 1 \cdot - 5 = 0$

Step 3.1.1

Multiply

$x$ by

$x$ .

$x^{2} + x \cdot - 5 - 1 x - 1 \cdot - 5 = 0$

Step 3.1.2

Move

$- 5$ to the left of

$x$ .

$x^{2} - 5 \cdot x - 1 x - 1 \cdot - 5 = 0$

Step 3.1.3

Rewrite

$- 1 x$ as

$- x$ .

$x^{2} - 5 x - x - 1 \cdot - 5 = 0$

Step 3.1.4

Multiply

$- 1$ by

$- 5$ .

$x^{2} - 5 x - x + 5 = 0$

Step 3.2

Subtract

$x$ from

$- 5 x$ .

$x^{2} - 6 x + 5 = 0$

Step 4

The standard quadratic equation using the given set of solutions

${1, 5}$ is

$y = x^{2} - 6 x + 5$ .

$y = x^{2} - 6 x + 5$
