0 = - 5 x^{2} + 225

x = 35, x = - 35

Decimal Notation

x = 6.70820 \dots, x = - 6.70820 \dots

Solution steps

0 = - 5 x^{2} + 225

Switch sides

- 5 x^{2} + 225 = 0

Move

225

to the right side

- 5 x^{2} = - 225

Divide both sides by

- 5

x^{2} = 45

For

x^{2} = f (a)

the solutions are

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

x = 45, x = - 45

45 = 35

- 45 = - 35

x = 35, x = - 35

(4 x - 5) (x + 2) = 4 x + 1

2 x (x + 3) = x^{2} + 3 x + 70

- x^{2} + 9 x - 3

(x - 2) (x - 3) = 30

y^{2} = 9 y
