(x^{2} - 1) = 3

x = 2, x = - 2

Solution steps

(x^{2} - 1) = 3

x^{2} - 1 = 3

Move

1

to the right side

x^{2} = 4

For

x^{2} = f (a)

the solutions are

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

x = 4, x = - 4

4 = 2

- 4 = - 2

x = 2, x = - 2

32 x^{2} - 3 x - 14 = (2 x - 1)^{2}

x, 4 x^{2} + 4 y^{2} - 16 x + 40 + 67 = 0

300 - 2 Q^{1} + Q^{2} = 60

6 x (4 x + 3) = 0

12 x^{2} - 320 x + 1500 = 0
