2 x^{2} = - 4 x

x = 0, x = - 2

Solution steps

2 x^{2} = - 4 x

Move

4 x

to the left side

2 x^{2} + 4 x = 0

Factor

2 x^{2} + 4 x : 2 x (x + 2)

2 x (x + 2) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 2 = 0

Solve

x + 2 = 0 : x = - 2

The solutions to the quadratic equation are:

x = 0, x = - 2

y^{2} - 15 y = - 54

1 + 10 x - 0.9 x^{2} = 0

x^{2} + 5 = 8

4 w^{2} - 7 w + 6 = 5

(5 - x)^{2} = 0
