36 x^{2} + 4 = 40

x = 1, x = - 1

Solution steps

36 x^{2} + 4 = 40

Move

4

to the right side

36 x^{2} = 36

Divide both sides by

36

x^{2} = 1

For

x^{2} = f (a)

the solutions are

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

x = 1, x = - 1

1 = 1

- 1 = - 1

x = 1, x = - 1

3 x^{2} + 8 = 13

x, f (x + 3) = x^{2} - 4 x + 4

x^{2} + 23 x - 140 = 0

(5 x - 4)^{2} = 81

4 x^{2} = - 9
