0 = - x^{2} + 4

x = 2, x = - 2

Solution steps

0 = - x^{2} + 4

Switch sides

- x^{2} + 4 = 0

Move

4

to the right side

- 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^{2} - 2 = 7

- 5 + 6 x - x^{2}

m^{2} + 2 m + 4 = 0

- x^{2} + 4 x

y, x = 2 y - y^{2}
