(x - 9) (5 x + 9) = 0

x = 9, x = - \frac{9}{5}

Solution steps

(x - 9) (5 x + 9) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 9 = 0 or 5 x + 9 = 0

Solve

x - 9 = 0 : x = 9

Solve

5 x + 9 = 0 : x = - \frac{9}{5}

The solutions to the quadratic equation are:

x = 9, x = - \frac{9}{5}

a (- a + 40) - 4 (a^{2} - 16) + 1 (- 5 a + 2) = 0

x^{2} - 12 x + 11 = 0

3 x = 4 (x - 9)
