Best ResponseYou've already chosen the best response.25*30 = 150. Can you think of two numbers which multiplied give you 150, and added give you 5?

Best ResponseYou've already chosen the best response.1I would first factor out a 5: 5(x²+x6). Now look for two numbers, with product 6 and sum 1 (because it is 1*x)

Best ResponseYou've already chosen the best response.0so would it be 5(x )(x ) ?

Best ResponseYou've already chosen the best response.1Yes, and put the numbers that have sum 1 and produc 6 on the blanks...

Best ResponseYou've already chosen the best response.0Don't you have to find the mutiples of 30. . . that sum to 5

Best ResponseYou've already chosen the best response.1You could also do it that way, but because I have factored out the 5, the other numbers can be smaller, so easier (imo)

Best ResponseYou've already chosen the best response.0I got confused with your method, I'm sorry.

Best ResponseYou've already chosen the best response.1Can you find the numbers? Their sum is 1, their product = 6, because you have to factor x²+1x6

Best ResponseYou've already chosen the best response.2Yes, factoring out the 5 does make it a little easier, and your factoring is correct. Good job!

Best ResponseYou've already chosen the best response.2I like leaving the extra factors in so I get practice for the times when I can't factor them out :)

Best ResponseYou've already chosen the best response.2Just about everything is easier with practice, so practicing the really hard stuff narrows the gap between easy and hard...

Best ResponseYou've already chosen the best response.1So you like torturing yourself... ;)
