8 x^{2} = 72 x

x = 0, x = 9

Solution steps

8 x^{2} = 72 x

Move

72 x

to the left side

8 x^{2} - 72 x = 0

Factor

8 x^{2} - 72 x : 8 x (x - 9)

8 x (x - 9) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x - 9 = 0

Solve

x - 9 = 0 : x = 9

The solutions to the quadratic equation are:

x = 0, x = 9

(3 x - 2)^{2} = (x + 1)^{2}

y, x^{2} - 14 x y + y^{2} = 14

2 x^{2} + 12 x + 6

x, x^{2} + 20 x + 900 I (x) = 180 x

x^{2} - 12 + 5 = 0
