Question

How do you solve x to the second power +7x=O

Answer 1

well the answer is 0 because if anything = 0 then it has to be multiplied by 0 so x = 0

Answer 2

x^2+7x=0
use the square root something....
(7/2)^2=49/4(add it to both sides)
x^2+7x+49/4=49/4
(x+7/2)^2=49/4
x+7/2=posinega 7/2
x=0 or x=-7
