- 6 x^{2} = x^{2} - 28

x = 2, x = - 2

Solution steps

- 6 x^{2} = x^{2} - 28

Move

x^{2}

to the left side

- 7 x^{2} = - 28

Divide both sides by

- 7

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

x + 1 = (3 x - 1)^{2}

x, x^{2} - 4 x + 13 = 0

n^{2} - \frac{1}{2} n = 3 n + 16

(2 x + 2) (6 \times (- 1)) = (3 x - 3) (4 x - 1)

8 x^{2} + 3 x + 3 = 0
