Question 104349
{{{-x^2 - x +3=-x+3}}} Start with the given equation



{{{-x^2 - x +3+x=cross(-x+x)+3}}} Add x to both sides




{{{-x^2 - x +3+x-3=cross(3-3)}}} Subtract 3 from both sides




{{{-x^2=0}}} Combine like terms



Now if you want to solve for x, then....




{{{x^2=0}}} Multiply both sides by -1 to remove the negative on the left side



{{{x=sqrt(0)}}} Take the square root of both sides



So our answer is {{{x=0}}}
