x^{2} = 8 x - 15

x = 3, x = 5

Solution steps

x^{2} = 8 x - 15

Move

15

to the left side

x^{2} + 15 = 8 x

Move

8 x

to the left side

x^{2} + 15 - 8 x = 0

Write in the standard form

a x^{2} + b x + c = 0

x^{2} - 8 x + 15 = 0

Factor

x^{2} - 8 x + 15 : (x - 3) (x - 5)

(x - 3) (x - 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 3 = 0 or x - 5 = 0

Solve

x - 3 = 0 : x = 3

Solve

x - 5 = 0 : x = 5

The solutions to the quadratic equation are:

x = 3, x = 5

x^{2} = 8 x + 8

- w^{2} - 3 w - 2 = - 5 w^{2}

n^{2} - 6 n - 7 = 0

x^{2} - 12 x + 64 = 0

b^{2} + 3 b = 0
