x^{2} - 16 = 0

x = - 4, x = 4

Solution steps

x^{2} - 16 = 0

Factor

x^{2} - 16 : (x + 4) (x - 4)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 4 = 0 or x - 4 = 0

Solve

x + 4 = 0 : x = - 4

Solve

x - 4 = 0 : x = 4

The solutions to the quadratic equation are:

x = - 4, x = 4

x^{2} + x + 2

x^{2} - 10 x + 21 = x - 3

- 9 x = x^{2} + 14

x, 2 (cos x)^{2} - 4 s in x cos x = - 1

5 x^{2} + 7 x + 9 = 5 - 3 x
