n^{2} + 7 n + 15 = 5

n = - 2, n = - 5

Solution steps

n^{2} + 7 n + 15 = 5

Move

5

to the left side

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

Factor

n^{2} + 7 n + 10 : (n + 2) (n + 5)

(n + 2) (n + 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

n + 2 = 0 or n + 5 = 0

Solve

n + 2 = 0 : n = - 2

Solve

n + 5 = 0 : n = - 5

The solutions to the quadratic equation are:

n = - 2, n = - 5

7 x^{2} - 5 x = 2

x^{2} + 12 x = 15

(x - 1)^{2} = \frac{4}{5}

- 3 w^{2} + 5 w - 15 = - 4 w^{2}

(7 x - 1) (2 x + 5) = 0
