(x + 9) (x - 7) = 0

x = - 9, x = 7

Solution steps

(x + 9) (x - 7) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 9 = 0 or x - 7 = 0

Solve

x + 9 = 0 : x = - 9

Solve

x - 7 = 0 : x = 7

The solutions to the quadratic equation are:

x = - 9, x = 7

2 x^{2} + 22 x + 36 = 0

y^{2} + 8 y + 11 = 0

14 - 5 x - x^{2} = 0

3^{2} + y^{2} = 5^{2}

x^{2} + 6 x = 3
