d^{2} = 21

d = 21, d = - 21

Decimal Notation

d = 4.58257 \dots, d = - 4.58257 \dots

Solution steps

d^{2} = 21

For

x^{2} = f (a)

the solutions are

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

d = 21, d = - 21

- 8 x^{2} = 392

\frac{1}{2} 9.8 (x - 40)^{2} = 0

12 x^{2} - 200 x + 630 = 0

225 = x^{2} + 7 x

0 = 3 X^{2} - 4 X + 5
