- 3 x^{2} - 7 = - 88

x = 33, x = - 33

Decimal Notation

x = 5.19615 \dots, x = - 5.19615 \dots

Solution steps

- 3 x^{2} - 7 = - 88

Move

7

to the right side

- 3 x^{2} = - 81

Divide both sides by

- 3

x^{2} = 27

For

x^{2} = f (a)

the solutions are

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

x = 27, x = - 27

27 = 33

- 27 = - 33

x = 33, x = - 33

2 x^{2} - 6 x + 12 = 0

x^{2} - 2 x + 2

4 (x - 1)^{2} = 36

5 x^{2} + 40 x = 0

5 (x^{2} - 9) - 5 = - 5
