(x + 4)^{2} + 4 = 85

x = 5, x = - 13

Solution steps

(x + 4)^{2} + 4 = 85

Move

4

to the right side

(x + 4)^{2} = 81

For

(g (x))^{2} = f (a)

the solutions are

g (x) = f (a), - f (a)

Solve

x + 4 = 81 : x = 5

Solve

x + 4 = - 81 : x = - 13

The solutions to the quadratic equation are:

x = 5, x = - 13

9 a^{2} - 64 b^{2}
