x^{2} - x = 20

x = - 4, x = 5

Solution steps

x^{2} - x = 20

Move

20

to the left side

x^{2} - x - 20 = 0

Factor

x^{2} - x - 20 : (x + 4) (x - 5)

(x + 4) (x - 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 4 = 0 or x - 5 = 0

Solve

x + 4 = 0 : x = - 4

Solve

x - 5 = 0 : x = 5

The solutions to the quadratic equation are:

x = - 4, x = 5

u^{2} - 3 u + 4 = 0

x^{2} + 2 x + 6

2 (a x^{2} - b^{3}) = b x (4 b - a)

2 x^{2} + x + 2

r^{2} + 5 r - 72 = 0
