Best ResponseYou've already chosen the best response.1we can multiply each one out and see what works, or perhaps we can work smarter

Best ResponseYou've already chosen the best response.1you see how the last term is \(2y\) right?

Best ResponseYou've already chosen the best response.0That's my problem, I get so confused multiplying everything out :( and yeah

Best ResponseYou've already chosen the best response.1that gets rid if b and d do you see why?

Best ResponseYou've already chosen the best response.0Yeah, that's actually a really cool loophole

Best ResponseYou've already chosen the best response.1\[ (5x + y)(2x + 3)\] last term will be \(3y\) so that is no good

Best ResponseYou've already chosen the best response.1same here \[ (5x + 3)(2x + y)\]

Best ResponseYou've already chosen the best response.0I figured it out, it's A

Best ResponseYou've already chosen the best response.1so we can try the first one \[ (3x + 2)(5x + y)\]

Best ResponseYou've already chosen the best response.0Graph of a cubic polynomial that falls to the left and rises to the right with graph touching x axis at negative 1 and x intercept at 1 Which of the following functions best represents the graph? f(x) = x3 + x2 − 4x − 4 f(x) = x3 + x2 − x − 1 f(x) = x3 + 3x2 − 4x − 12 f(x) = x3 + 2x2 − 2x − 1

Best ResponseYou've already chosen the best response.1you see how it only touches where \(x=1\)?

lalaland_lauren

Best ResponseYou've already chosen the best response.0Yeah, and where x=1

Best ResponseYou've already chosen the best response.1actually there is a difference, where \(x=1\) it CROSSES the axis, at \(x=1\) it comes up, touches it, but does not cross, goes back down

Best ResponseYou've already chosen the best response.1so it has to zeros, one at \(x=1\) and one at \(x=1\) because it crosses at \(x=1\) one factor is \((x1)\)

misty1212

Best ResponseYou've already chosen the best response.1because it touches at \(x=1\) then the factor looks like \((x+1)^2\)

Best ResponseYou've already chosen the best response.1lol "has two zeros" i meant

Best ResponseYou've already chosen the best response.1final job is to multiply \[(x+1)^2(x1)\] to see what we get i would cheat!!

Best ResponseYou've already chosen the best response.0Which shows 602 − 402 being evaluated using the difference of squares method? 602 − 402 = (3600 + 1600)(3600 − 1600) = 10,400,000 602 − 402 = 3600 − 1600 = 2,000 602 − 402 = (60 − 40)2 = 202 = 400 602 − 402 = (60 + 40)(60 − 40) = (100)(20) = 2,000
