z^{2} - 2 z - 35 = 0

z = 7, z = - 5

Solution steps

z^{2} - 2 z - 35 = 0

Move

35

to the right side

z^{2} - 2 z = 35

Rewrite in the form

(x + a)^{2} = b

(z - 1)^{2} = 36

For

the solutions are

f (x) = a, - a

Solve

z - 1 = 36 : z = 7

Solve

z - 1 = - 36 : z = - 5

The solutions to the quadratic equation are:

z = 7, z = - 5

- 3 x^{2} + 5 x - 7 = 0

\frac{1}{2} \cdot \frac{1}{32} (10 - x) (10 - x) = 0.3

- 32 x^{2} + 19 x + 17 = 0

x^{2} + x + 1.5 = 0

5 x (x - 1) = 2 (x^{2} - 7 x - 8)
