k^{2} + 15 k = - 56

k = - 7, k = - 8

Solution steps

k^{2} + 15 k = - 56

Move

56

to the left side

k^{2} + 15 k + 56 = 0

Factor

k^{2} + 15 k + 56 : (k + 7) (k + 8)

(k + 7) (k + 8) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

k + 7 = 0 or k + 8 = 0

Solve

k + 7 = 0 : k = - 7

Solve

k + 8 = 0 : k = - 8

The solutions to the quadratic equation are:

k = - 7, k = - 8

(x + 5) (x - 1) - 7 (x + 1) = - 3 x - 3

p^{2} + 3 p + 2 = 0

x, x (x + 5) = - 6

x^{2} - 2 x = \frac{5}{2}

x, 5 x^{2} + 10 x + 4 = 0
