r (r + 4) = 0

r = 0, r = - 4

Solution steps

r (r + 4) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

r = 0 or r + 4 = 0

Solve

r + 4 = 0 : r = - 4

The solutions to the quadratic equation are:

r = 0, r = - 4

2 (x^{2} - 2 x) = 5

x^{2} - 13 + 40 = 0

- x^{2} + 2 x = 3

0.0057 v^{2} + 0.13 v - 100 = 0

v^{2} + 10 v + 24 = 0
