40 = x^{2}

x = 210, x = - 210

Decimal Notation

x = 6.32455 \dots, x = - 6.32455 \dots

Solution steps

40 = x^{2}

Switch sides

x^{2} = 40

For

x^{2} = f (a)

the solutions are

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

x = 40, x = - 40

40 = 210

- 40 = - 210

x = 210, x = - 210

xx + x + x = 24

3 x^{2} - 14 x - 1 = 0

24 x (x + 1) = 4 x^{2} - 7

4 x^{2} - 11 = 4 x

4 (x^{2} - 7) - 10 = - 13
