(x - 2)^{2} - 20 = - 45

x = 5 i + 2, x = - 5 i + 2

Solution steps

(x - 2)^{2} - 20 = - 45

Move

20

to the right side

(x - 2)^{2} = - 25

For

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

the solutions are

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

Solve

x - 2 = - 25 : x = 5 i + 2

Solve

x - 2 = - - 25 : x = - 5 i + 2

The solutions to the quadratic equation are:

x = 5 i + 2, x = - 5 i + 2

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

(x + 8) (x - 9) = 0

x^{2} + 4 x + 20 = 10

x^{2} - x - 3

\frac{2 x ^{2}}{5} = 90
