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

x = 7 + 9, x = - 7 + 9

Decimal Notation

x = 11.64575 \dots, x = 6.35424 \dots

Solution steps

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

Divide both sides by

3

(x - 9)^{2} = 7

For

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

the solutions are

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

Solve

x - 9 = 7 : x = 7 + 9

Solve

x - 9 = - 7 : x = - 7 + 9

The solutions to the quadratic equation are:

x = 7 + 9, x = - 7 + 9

- 2 x^{2} + 9 x - 9 = 0

(X^{1} + X^{2}) = 5

3 x^{2} - 90 x + 243 = 0

x^{2} - 4 x - 2 = 3

x^{2} = 4 x - 14
