2 x^{2} = 90

x = 35, x = - 35

Decimal Notation

x = 6.70820 \dots, x = - 6.70820 \dots

Solution steps

2 x^{2} = 90

Divide both sides by

2

x^{2} = 45

For

x^{2} = f (a)

the solutions are

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

x = 45, x = - 45

45 = 35

- 45 = - 35

x = 35, x = - 35

5 x^{2} = 33 x - 40

3 x = 4 - x^{2}

(x) (x + 5) = 456

169 x^{2} - 9 = 0

4 v^{2} - 24 v = 0
