Factor Completely: x^2 + 25 (x + 5)(x + 5) (x + 5)(x − 5) (x − 5)(x − 5) Prime
 one year ago

sjerman1Best ResponseYou've already chosen the best response.1
so the easiest way to do this is to multiply out the factors you have there you know that it needs to multiply out to a positive 25

mikaa_toxica13Best ResponseYou've already chosen the best response.0
okay. i think its B.

sjerman1Best ResponseYou've already chosen the best response.1
now also have you go over the list of items that are prime?

sjerman1Best ResponseYou've already chosen the best response.1
because if you multiply 5*5 you get 25 not +25

sjerman1Best ResponseYou've already chosen the best response.1
this factor is prime, im not sure if you were looking up or waiting for a responce but this one can not be factored
 one year ago

sjerman1Best ResponseYou've already chosen the best response.1
to justify this you can take the only one that will work, or rather come close, would be (x + 5)(x + 5) or (x − 5)(x − 5) and both of these would give you a middle term either 10x or +10x

i was trying to look it up :/ i jus cant really get it

sjerman1Best ResponseYou've already chosen the best response.1
for this, i know its going to be annoying for now, it will be a lot easier the more you do this, but multiply out the terms to find out what it comes out to

sjerman1Best ResponseYou've already chosen the best response.1
(x + 5)(x + 5) = x^2+10x+25 (x + 5)(x − 5) = x^225 (x − 5)(x − 5) = x^210x+25
 one year ago

sjerman1Best ResponseYou've already chosen the best response.1
then you can see, oh none of these match the answer, therefore it's prime.

oh okay thanks ! Factor Completely: 36x^2 − 25 (6x − 5)(x + 5) (6x + 5)(6x + 5) (6x − 5)(6x − 5) < answer (6x + 5)(6x − 5) Factor Completely: 3x^2 − 21 3(x^2 − 7) < answer 3(x + 7)(x − 7) 3(x + 7)(x − 3) Prime

sjerman1Best ResponseYou've already chosen the best response.1
welllllll. on the first one, the easy thing to look at tis you need to have a 25 so what multiplies to give you a 25

this one is not prime.

okay then its gotta be B

Factor Completely: 2x^2 − 32 Prime 2(x^2 − 16) 2(x + 4)(x + 4) 2(x + 4)(x − 4)<answer, because 2(x^216) > 2(x+4)(x4)

sjerman1Best ResponseYou've already chosen the best response.1
keep in mind that 6*6 gives you 36
 one year ago

sjerman1Best ResponseYou've already chosen the best response.1
but the easiest way to look at this is x2 − 36, there is no middle term, this means there has to be one factor is that x + something and x  something to make the middle term go away
