4 x^{2} - 90 = 10

x = 5, x = - 5

Solution steps

4 x^{2} - 90 = 10

Move

90

to the right side

4 x^{2} = 100

Divide both sides by

4

x^{2} = 25

For

x^{2} = f (a)

the solutions are

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

x = 25, x = - 25

25 = 5

- 25 = - 5

x = 5, x = - 5

x, 2 x^{2} + y^{2} + 3 \cdot x \cdot y = 1

x^{2} - 10 x - 1 = 0

(2 x + 3)^{2} - 4 = 0

- 3 x + 18 = x^{2}

b^{2} + 64 = 0
