what is x squared plus 2x=0

Question

I am trying to figure out the problem x(x+2)=0 . please help

Answer 1

x(x+2)=0

how do you turn a number to zero? you multiple it by zero. since we have multiplication on the left, one of the multiplied numbers has to be 0. this leads to 2 possible answers:

I. x=0. which is the first answer.

II. x+2=0 . decrease both sides of the equation by 2

x+2=0 \-2

x=-2 . that's the second answer.
