X^{2} + X - 30 = 0

X = 5, X = - 6

Solution steps

X^{2} + X - 30 = 0

Move

30

to the right side

X^{2} + X = 30

Rewrite in the form

(x + a)^{2} = b

(X + \frac{1}{2})^{2} = \frac{121}{4}

For

the solutions are

f (x) = a, - a

Solve

X + \frac{1}{2} = \frac{121}{4} : X = 5

Solve

X + \frac{1}{2} = - \frac{121}{4} : X = - 6

The solutions to the quadratic equation are:

X = 5, X = - 6

2 (x^{2} + 2) = 22

6 x^{2} = 4

5 - 6 x + x^{2} = 0

3 t^{2} - 2 t = 0

8 x^{2} - 14 x - 4 = 0
