686 = - 0.25 q^{2} + 750

q = 16, q = - 16

Solution steps

686 = - 0.25 q^{2} + 750

Switch sides

- 0.25 q^{2} + 750 = 686

Move

750

to the right side

- 0.25 q^{2} = - 64

Divide both sides by

- 0.25

q^{2} = 256

For

x^{2} = f (a)

the solutions are

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

q = 256, q = - 256

256 = 16

- 256 = - 16

q = 16, q = - 16

x, x^{2} + y^{2} + z^{2} = 49

x, z x^{2} - x + 5 - 3 z = 0

m^{2} - 7 m + 2 = 0

3 x^{2} + 35 = 7 x^{2} - 4 x

\frac{1}{2} x^{2} + x = 5
