\frac{1}{2} x^{2} - 12 = 21

x = 66, x = - 66

Decimal Notation

x = 8.12403 \dots, x = - 8.12403 \dots

Solution steps

\frac{1}{2} x^{2} - 12 = 21

Move

12

to the right side

\frac{1}{2} x^{2} = 33

Multiply both sides by

2

x^{2} = 66

For

x^{2} = f (a)

the solutions are

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

x = 66, x = - 66

a x + b y + a y + b x

4 y^{2} - 25 x^{2}

2 x (3 x + 1) = 7

- \frac{2}{5} + \frac{1}{2}

5 x - 11 = 19
