7 x^{2} = 56

x = 22, x = - 22

Decimal Notation

x = 2.82842 \dots, x = - 2.82842 \dots

Solution steps

7 x^{2} = 56

Divide both sides by

7

x^{2} = 8

For

x^{2} = f (a)

the solutions are

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

x = 8, x = - 8

8 = 22

- 8 = - 22

x = 22, x = - 22

2 x^{2} + 10 x - 16 = 0

3 x^{2} - 6 x + 80 = - 4

5 (3 x - 2)^{2} + 27 = 32

(x 3)^{2} + x^{2} = 1

4 y^{2} = - 12 y - 9
