(x - 4)^{2} = 21

x = 21 + 4, x = - 21 + 4

Decimal Notation

x = 8.58257 \dots, x = - 0.58257 \dots

Solution steps

(x - 4)^{2} = 21

For

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

the solutions are

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

Solve

x - 4 = 21 : x = 21 + 4

Solve

x - 4 = - 21 : x = - 21 + 4

The solutions to the quadratic equation are:

x = 21 + 4, x = - 21 + 4

5 + 4

2 x^{3} - 6 x

2 x^{2} + 12 x + 15 = 0

64 x^{2} - 1 = 0
