2 - x^{2} = - 7

x = 3, x = - 3

Solution steps

2 - x^{2} = - 7

Move

2

to the right side

- x^{2} = - 9

Divide both sides by

- 1

x^{2} = 9

For

x^{2} = f (a)

the solutions are

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

x = 9, x = - 9

9 = 3

- 9 = - 3

x = 3, x = - 3

x^{2} + 8 x - 80 = 0

\frac{x ^{2} + x}{2} = 0

u^{2} = - 64

\frac{3}{8} x^{2} + 3 x + \frac{9}{2} = 0

3 x^{2} - 40 = 7 x
