3 (x^{2} - 7) - 4 = - 7

x = 6, x = - 6

Decimal

x = 2.44948 \dots, x = - 2.44948 \dots

Solution steps

3 (x^{2} - 7) - 4 = - 7

Move

4

to the right side

3 (x^{2} - 7) = - 3

Divide both sides by

3

x^{2} - 7 = - 1

Move

7

to the right side

x^{2} = 6

For

x^{2} = f (a)

the solutions are

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

x = 6, x = - 6

y, y^{2} = x^{3} - x

4 x^{2} + 12 x - 5

2 - 25 x^{2} = 625 x^{2}

y, y^{2} - 3 x^{2} = 0

4 a^{2} - 14 a + 13 = 2
