g^{2} + 2 g - 15 = 0

g = 3, g = - 5

Solution steps

g^{2} + 2 g - 15 = 0

Move

15

to the right side

g^{2} + 2 g = 15

Rewrite in the form

(x + a)^{2} = b

(g + 1)^{2} = 16

For

the solutions are

f (x) = a, - a

Solve

g + 1 = 16 : g = 3

Solve

g + 1 = - 16 : g = - 5

The solutions to the quadratic equation are:

g = 3, g = - 5

5 r^{2} - 5 r = - 8

x, x^{2} y^{2} = - 1

x^{2} - 14 = 2 x

8 t^{2} - 2 t = 3

3 (x + 1)^{2} = 81
