(x - 21)^{2} = 28

x = 27 + 21, x = - 27 + 21

Decimal Notation

x = 26.29150 \dots, x = 15.70849 \dots

Solution steps

(x - 21)^{2} = 28

For

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

the solutions are

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

Solve

x - 21 = 28 : x = 27 + 21

Solve

x - 21 = - 28 : x = - 27 + 21

The solutions to the quadratic equation are:

x = 27 + 21, x = - 27 + 21

4 x^{2} - 14 x + 7 = 4 - x

5 x^{2} - 40 x - 97 = 3

- 3 x^{2} + 8 x - 5 = 0

4 z + z^{2} + 12 = 0

1 - x (- 5) - (- 5) + x^{2} = 0
