3 (4 x - 6)^{2} - 21 = - 9

x = 2, x = 1

Solution steps

3 (4 x - 6)^{2} - 21 = - 9

Move

21

to the right side

3 (4 x - 6)^{2} = 12

Divide both sides by

3

(4 x - 6)^{2} = 4

For

(g (x))^{2} = f (a)

the solutions are

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

Solve

4 x - 6 = 4 : x = 2

Solve

4 x - 6 = - 4 : x = 1

The solutions to the quadratic equation are:

x = 2, x = 1

x^{2} + 1 = 4 x^{2}

- 15 x = 45 x^{2}

x, 5 x^{2} + 5 y^{2} + 10 x - 10 y + 20 = 0

m^{2} = 0

- x^{2} = - 4
