Answer..
Equation can be written as
X^2 + x -110 =0
X^2 + 11x -10x -110=0
X(x+11) -10(x+11)=0
(X-10)(x+11)=0
X-10=0 and x +11=0
X=10,-11

Answer:
(x+11)(x-10)
Step-by-step explanation:
First we rearrange the terms according to degree. We get (-x^2-x+110).
We split the middle term x to get -11x+10x which is equal to -x and when multiplied, we get -110x^2. Note that when you multiply the first and last terms, i.e -x^2 and 110 ,you get -110x^2 as well. So you get -x^2+10x-11x+110. If you take -x common in the first two terms and +10 in the last two, you get -x(x+11)+10(x+11). Now if you take (x+11) common, you get (x+11)(-x+10) or (x+11)(10-x), which is the final answer.Hope it helped you!
