x^{2} - 81 = 0

x = - 9, x = 9

Solution steps

x^{2} - 81 = 0

Factor

x^{2} - 81 : (x + 9) (x - 9)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 9 = 0 or x - 9 = 0

Solve

x + 9 = 0 : x = - 9

Solve

x - 9 = 0 : x = 9

The solutions to the quadratic equation are:

x = - 9, x = 9

36 q^{2} - 333 q + 81 = 0

s^{2} + 2 s + 10

4 x^{2} + 69 = 28 x

x^{2} - x - 35 = - x + 1

4 x^{2} - 16 x - 33
