solve for

z, - 7 z^{2} = - 28

z = 2, z = - 2

Solution steps

- 7 z^{2} = - 28

Divide both sides by

- 7

z^{2} = 4

For

x^{2} = f (a)

the solutions are

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

z = 4, z = - 4

4 = 2

- 4 = - 2

z = 2, z = - 2

x, 45 = x \cdot 180

x, ∣ 2 x - 3 ∣ < 3

\frac{25}{π}

x, - 4 (3 x + 1) + x - 3 = 15

3 x^{2} - 10 x + 3 = 0
