y^{2} - y - 20 = 0

y = - 4, y = 5

Solution steps

y^{2} - y - 20 = 0

Factor

y^{2} - y - 20 : (y + 4) (y - 5)

(y + 4) (y - 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

y + 4 = 0 or y - 5 = 0

Solve

y + 4 = 0 : y = - 4

Solve

y - 5 = 0 : y = 5

The solutions to the quadratic equation are:

y = - 4, y = 5

- 3 x^{2} = 24 x + 48

x^{2} + 10 x + 4

x^{2} - 3 x = 9 x

x, x^{2} = y^{4} - 77
