x^{2} + 2 x - 35 = 0

x = 5, x = - 7

Solution steps

x^{2} + 2 x - 35 = 0

Move

35

to the right side

x^{2} + 2 x = 35

Rewrite in the form

(x + a)^{2} = b

(x + 1)^{2} = 36

For

the solutions are

f (x) = a, - a

Solve

x + 1 = 36 : x = 5

Solve

x + 1 = - 36 : x = - 7

The solutions to the quadratic equation are:

x = 5, x = - 7

18 x^{2} + 25 x - 3 = 0

9^{2} + 2^{2} = x^{2}

(x + 4) (x + 6) = 0

21 = - x^{2} + 10 x

2 x^{2} - 16 x + 24
