40 = y^{2}

y = 210, y = - 210

Decimal Notation

y = 6.32455 \dots, y = - 6.32455 \dots

Solution steps

40 = y^{2}

Switch sides

y^{2} = 40

For

x^{2} = f (a)

the solutions are

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

y = 40, y = - 40

40 = 210

- 40 = - 210

y = 210, y = - 210

n^{2} - 5 n - 6 = 0

1.25 x^{2} - 25 x + 5 = 0

4 x^{2} - x + 1 = x + 3 x^{2}

y^{2} = - 5

x, x^{2} = 9
