x^{2} + 8 x + 7 = 0

x = - 1, x = - 7

Solution steps

x^{2} + 8 x + 7 = 0

Move

7

to the right side

x^{2} + 8 x = - 7

Rewrite in the form

(x + a)^{2} = b

(x + 4)^{2} = 9

For

the solutions are

f (x) = a, - a

Solve

x + 4 = 9 : x = - 1

Solve

x + 4 = - 9 : x = - 7

The solutions to the quadratic equation are:

x = - 1, x = - 7

(x + 2)^{2} = x^{2} + (x + 1)^{2}

y, e^{x} y + x^{2} e^{- x} = y^{2}

(2 x + 3) (x + 4) = x

x^{2} - 20 x - 99 = 0

3 x (x - 5) + (x - 3) (x - 2) = - 18
