x^{2} - 9 x - 20 = - 2 x - 2

x = - 2, x = 9

Solution steps

x^{2} - 9 x - 20 = - 2 x - 2

Move

2

to the left side

x^{2} - 9 x - 18 = - 2 x

Move

2 x

to the left side

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

(y + 14)^{2} + y^{2} - 25 = 0

y, x^{2} + y^{2} = - 5

y, x^{2} + y^{2} = - 4

a (x) = (x - 3) (4 x + 1) + 2 (3 - x) (x + 2)

- 12 x^{2} = 720
