- 4 x^{2} + 5 = - 59

x = 4, x = - 4

Solution steps

- 4 x^{2} + 5 = - 59

Move

5

to the right side

- 4 x^{2} = - 64

Divide both sides by

- 4

x^{2} = 16

For

x^{2} = f (a)

the solutions are

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

x = 16, x = - 16

16 = 4

- 16 = - 4

x = 4, x = - 4

9 x^{2} + 5 x = 3

(3 x + 2) (x - 7) = 0

- 2 x^{2} + 8 x + 4 = 0

4 u^{2} - 11 u - 3 = 0

7 x^{2} + 4 x - 6 = 0
