x^{2}-4x-x^{2}-2x=-1+1
Combine 4x^{2} and -3x^{2} to get x^{2}.
-4x-2x=-1+1
Combine x^{2} and -x^{2} to get 0.
-6x=-1+1
Combine -4x and -2x to get -6x.
-6x=0
Add -1 and 1 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since -6 is not equal to 0, x must be equal to 0.
