2 x^{2} - 90 = 0

x = 35, x = - 35

Decimal Notation

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

Solution steps

2 x^{2} - 90 = 0

Move

90

to the right side

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

∣ x - 3 ∣ = ∣ x + 7 ∣

4 (v + 1) - v = 3 (v - 1) + 3

(7 - 6 i)^{2}

5 x^{2} + 8 x = 0

X^{2} + 1 = 0
