(x - 2)^{2} = 21

x = 21 + 2, x = - 21 + 2

Decimal Notation

x = 6.58257 \dots, x = - 2.58257 \dots

Solution steps

(x - 2)^{2} = 21

For

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

the solutions are

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

Solve

x - 2 = 21 : x = 21 + 2

Solve

x - 2 = - 21 : x = - 21 + 2

The solutions to the quadratic equation are:

x = 21 + 2, x = - 21 + 2

4 x - 6 = 0

\frac{( x + 8 ) ( x - 6 )}{x - 1} \geq 0

x^{2} + 8 x + 1 = 0

3 x - 5 = 16

4 x^{2} - 16 x + 12
