(FOR D) ooh you can multiply by the reciprocal if that helps cause looking at it like that hurts me
(X^4)(X^4)over (X+10) * (X+6)(X+10) 0ver (X^4)
so you can see that some cancels out (bold)
so then it'd be
X^4 (X+6)
hUh ?? are we looking at the same exercise what
sorry i did the simplifying in one step. we're trying to get factors that cancel out, so we factor out some of the expressions. so for the X^8, we make that (X^4)times (X^4) cause those are equivilent to (X^8 ) but then we can cancel out one of the (X^4).
same with the X^2+16x+60 which is equivilent to (X+6) times (X+10)
and then, to make it easier to see, you can multiply by the reciprical which is the same as dividing. so 1/x divided by 2/y is the same as 1/x times y/2. so i switched the parts in D like that because looking at that tower of division hurts my eyes
then, we can see that the (X+10)s cancel and the (X^4) because if you have something on the top and bottom they cancel out. so 1/x divided by 2/x could be written as 1/x times x/2 which would cancel to 1/2 because the x's would cancel out (for example)
o yes I see
