Best ResponseYou've already chosen the best response.1I got: (x+1)(x+9)

Best ResponseYou've already chosen the best response.2let's expand out (x+1)(x+9) to see what we get dw:1438385037947:dw

Best ResponseYou've already chosen the best response.2then you add up all the terms x^2 + x + 9x + 9 = x^2 + 10x + 9 that shows us x^2 + 10x + 9 factors to (x+1)(x+9)

Best ResponseYou've already chosen the best response.1Yeah, but the original equation is what I've posted first and factored out and came out to as (x+1)(x+9)

Best ResponseYou've already chosen the best response.1Wait, so I factored it wrong?

Best ResponseYou've already chosen the best response.2if you have a 2 outside, then it works because 2(x+1)(x+9) = 2(x^2 + 10x + 9) = 2x^2 + 20x + 18

Best ResponseYou've already chosen the best response.1Ohh! Ok! I think that's what I was missing..For this problem: \[2x^2+6x36\] I got: 2(x3)(x+6) Is that correct?

Best ResponseYou've already chosen the best response.1Anyways.... I need help with this one: \[x^220x13\] I'm guessing it could be prime?

Best ResponseYou've already chosen the best response.2ways to multiply to 13 1*13 1*(13) none of those pairs add to 20 1+13 = 12 1+(13) = 12 so yes it is prime

Best ResponseYou've already chosen the best response.0You can use the quadratic formula.

Best ResponseYou've already chosen the best response.2specifically you can use the discriminant formula D = b^2  4ac if D is a positive number and a perfect square, then you can factor

Best ResponseYou've already chosen the best response.1I know I can, but I do not want to take it that far alongside, that's not what I'm required to do..

Best ResponseYou've already chosen the best response.1\[3x^227x+54\] This can be factored out, right? No, all I need to do is factor not solving any further..

jim_thompson5910

Best ResponseYou've already chosen the best response.2yes that can be factored. if you're stuck, try factoring out the GCF 3

Best ResponseYou've already chosen the best response.1Ok, lemme see what I can get lol. I thought so about 3 lol.. Don't do the problem for me.. I wanna do it haha.

Best ResponseYou've already chosen the best response.1Ok, so I got: \[3(x^29x+18)\] Does this seem right? If it does, not all of it has been factored out, correct?

jim_thompson5910

Best ResponseYou've already chosen the best response.2so far so good. can you factor the inside stuff at all?

YanaSidlinskiy

Best ResponseYou've already chosen the best response.1Yes, I think so.. A 2?

Best ResponseYou've already chosen the best response.2yes don't forget about the 3 out front

Best ResponseYou've already chosen the best response.0Since you factored out a 3.
