x^{2} + 2 x = 15

x = 3, x = - 5

Solution steps

x^{2} + 2 x = 15

Move

15

to the left side

x^{2} + 2 x - 15 = 0

Factor

x^{2} + 2 x - 15 : (x - 3) (x + 5)

(x - 3) (x + 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 3 = 0 or x + 5 = 0

Solve

x - 3 = 0 : x = 3

Solve

x + 5 = 0 : x = - 5

The solutions to the quadratic equation are:

x = 3, x = - 5

x^{2} + 8 x - 30 = 18

- x^{2} + 14 x + 94 = 0

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

- 4 x^{2} + x - 1 = 0

8 x^{2} - 20 x = 0
