X^2+4X-2=(X-1)(X+5)
We move all terms to the left:
X^2+4X-2-((X-1)(X+5))=0
We multiply parentheses ..
X^2-((+X^2+5X-1X-5))+4X-2=0
We calculate terms in parentheses: -((+X^2+5X-1X-5)), so:We add all the numbers together, and all the variables
(+X^2+5X-1X-5)
We get rid of parentheses
X^2+5X-1X-5
We add all the numbers together, and all the variables
X^2+4X-5
Back to the equation:
-(X^2+4X-5)
X^2+4X-(X^2+4X-5)-2=0
We get rid of parentheses
X^2-X^2+4X-4X+5-2=0
We add all the numbers together, and all the variables
3!=0
