solve for

x, 7 = 2 x^{2} - 11

x = 3, x = - 3

Solution steps

7 = 2 x^{2} - 11

Switch sides

2 x^{2} - 11 = 7

Move

11

to the right side

2 x^{2} = 18

Divide both sides by

2

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

2 x^{2} - 8 x + 7 = 0

0 = t^{2} - 6 t + 5

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

a, 70 a^{2} - 149 ab + 70 b^{2} = 0

8 x^{2} - 55 x + 42 = 0
