How do you solve #x^2 + 4x = 0#?

Answer 1

Kennedy Adams

The solutions are :
#color(blue)( x=0#
# color(blue)(x=-4#

#x^2 + 4x = 0#

#x# is common to both terms. #color(blue)(x ) * ( x +4 ) = 0#

Equating each of the factors to #0# will provide the solutions.

To solve the equation x^2 + 4x = 0:

Factor out the common factor x: x(x + 4) = 0.
Set each factor equal to zero and solve for x:
- Setting x = 0: x = 0.
- Setting x + 4 = 0: x = -4.

So, the solutions to the equation are x = 0 and x = -4.

To solve the equation (x^2 + 4x = 0), first factor out the common factor, which is (x). Then, solve for (x) by setting each factor equal to zero. The solutions are (x = 0) and (x = -4).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
