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

x = 2, x = - 9

Solution steps

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

Factor

x^{2} + 7 x - 18 : (x - 2) (x + 9)

(x - 2) (x + 9) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 2 = 0 or x + 9 = 0

Solve

x - 2 = 0 : x = 2

Solve

x + 9 = 0 : x = - 9

The solutions to the quadratic equation are:

x = 2, x = - 9

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

8 x^{2} - 20 x = 0

- \frac{23}{40} x^{2} + \frac{1}{2} x + 10 = 0

8 z^{2} - 9 z + 16 = 0

- 6 m^{2} = 48
