X^{2} - 1 = 3

X = 2, X = - 2

Solution steps

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

6 (2 x - 1) (3 x - 1) - 12 x^{2} = 7 x (2 x - 1)

x^{2} - 7 x - 14 = 0

2 x^{2} + 15 x + 19 = 0

5 \cdot 5 = \frac{e ^{2}}{4}

x, 2 x^{2} - 2 y^{2} = 0
