x^{2} + 16 x + 51 = 0

x = 13 - 8, x = - 13 - 8

Decimal Notation

x = - 4.39444 \dots, x = - 11.60555 \dots

Solution steps

x^{2} + 16 x + 51 = 0

Move

51

to the right side

x^{2} + 16 x = - 51

Rewrite in the form

(x + a)^{2} = b

(x + 8)^{2} = 13

For

the solutions are

f (x) = a, - a

Solve

x + 8 = 13 : x = 13 - 8

Solve

x + 8 = - 13 : x = - 13 - 8

The solutions to the quadratic equation are:

x = 13 - 8, x = - 13 - 8

x^{2} + 9 = - 40

y, x^{2} y^{2} - 2 x y^{2} + y^{2} - x = 0

5 t^{2} + 10 t - 40 = 0

- 33 x^{2} + 14 x + 5 = 0

16 x^{2} - 8 x + 1 = 0
