x (x - 5) = 4 x

x = 0, x = 9

Solution steps

x (x - 5) = 4 x

Move

4 x

to the left side

x (x - 5) - 4 x = 0

Factor

x (x - 5) - 4 x : x (x - 9)

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

16 x^{2} + 22 = 0

x^{2} + a x - b x = ab

3 x^{2} - 60 x + 741 = 0

10 + x (x - 2) = 2

8 v^{2} + 8 = - 32
