3 y^{2} - 7 = 20

y = 3, y = - 3

Solution steps

3 y^{2} - 7 = 20

Move

7

to the right side

3 y^{2} = 27

Divide both sides by

3

y^{2} = 9

For

x^{2} = f (a)

the solutions are

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

y = 9, y = - 9

9 = 3

- 9 = - 3

y = 3, y = - 3

- \frac{14}{- 4}

x^{2} - 2 x \leq 0

4 p^{2} - 12 p + 9 = 0

9 (- 4 + 2 v) + 7 v = - 211

(x + 2) (x - 1) (x - 3) > 0
