x^{2} + 10 x + 7 = 0

x = 32 - 5, x = - 32 - 5

Decimal Notation

x = - 0.75735 \dots, x = - 9.24264 \dots

Solution steps

x^{2} + 10 x + 7 = 0

Move

7

to the right side

x^{2} + 10 x = - 7

Rewrite in the form

(x + a)^{2} = b

(x + 5)^{2} = 18

For

the solutions are

f (x) = a, - a

Solve

x + 5 = 18 : x = 32 - 5

Solve

x + 5 = - 18 : x = - 32 - 5

The solutions to the quadratic equation are:

x = 32 - 5, x = - 32 - 5

5 + 11 + 17 + 23 + (6 n - 1) = n (3 n + 2)

x^{2} + 6 x + 25

x^{2} + 6 x + 34

7 x^{2} - 8 x - 15 = 0

(3 x - 1) (x + 4) = 0
