x^{2} + 7 x = 18

x = 2, x = - 9

Solution steps

x^{2} + 7 x = 18

Move

18

to the left side

x^{2} + 7 x - 18 = 0

Factor

x^{2} + 7 x - 18 : (x - 2) (x + 9)

(x - 2) (x + 9) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 2 = 0 or x + 9 = 0

Solve

x - 2 = 0 : x = 2

Solve

x + 9 = 0 : x = - 9

The solutions to the quadratic equation are:

x = 2, x = - 9

u^{2} + 8 u

- 3 x^{2} + 7 x + 2 = 0

u^{2} + 2 u

x^{2} + 19 x + 3 = - 10

6 x^{2} - 6 x = - 1
