- 4 = - x^{2}

x = 2, x = - 2

Solution steps

- 4 = - x^{2}

Switch sides

- x^{2} = - 4

Divide both sides by

- 1

x^{2} = 4

For

x^{2} = f (a)

the solutions are

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

x = 4, x = - 4

4 = 2

- 4 = - 2

x = 2, x = - 2

(x - 6)^{2} = - 32

2 x^{2} - 12 x - 9

(x - 10)^{2} + x (x + 17) = 104

25 a = 10 a^{2}

x^{2} - 4 x = 3 x - 12
