20 = y^{2}

y = 25, y = - 25

Decimal Notation

y = 4.47213 \dots, y = - 4.47213 \dots

Solution steps

20 = y^{2}

Switch sides

y^{2} = 20

For

x^{2} = f (a)

the solutions are

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

y = 20, y = - 20

20 = 25

- 20 = - 25

y = 25, y = - 25

40 = (x + 20) (x - 20)

0 = - 3 x^{2}

9 - x^{2} - x - 3 = 0

2 x^{2} - 7 x = 3

2 x^{2} - 7 x = 9
