4 x^{2} - 9 = 7

x = 2, x = - 2

Solution steps

4 x^{2} - 9 = 7

Move

9

to the right side

4 x^{2} = 16

Divide both sides by

4

x^{2} = 4

For

x^{2} = f (a)

the solutions are

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

x = 4, x = - 4

4 = 2

- 4 = - 2

x = 2, x = - 2

- 4 x^{2} + 64 x + 256 = 0

x^{2} - 17 x + 52 = 0

- \frac{1}{2} x^{2} - x + \frac{3}{2} = 0

2 x^{2} + 11 x + 15

2 x^{2} + 12 x - 13 = 0
