Best ResponseYou've already chosen the best response.0from this line 3x(x+3)2(x+3)=0 if u factorise (x+3) , u may get

Best ResponseYou've already chosen the best response.0my teacher makes us do a big x. so what multiplies to 12 and adds to 7. i got 9 and 2 so (x+9) (x2) how do i go on from there

Best ResponseYou've already chosen the best response.0solve by factoring \[3x ^{2}+7x6=0\] step one. FACTOR. multiply 6 and 3 to get 18. now find what multiplies to 18 make sure that they also add to get 7. 9 and 2 MULTIPLY together and make 18 and ADD to make 7. so you make the equation (x+9)(x2)=0 but you still have to do more for the rest of the problem. so im confused on the rest

Best ResponseYou've already chosen the best response.0so it would be \[3x ^{2}+(x+9)(x2)6=0 ?\] that makes no sense

Best ResponseYou've already chosen the best response.0no, when u factorise by ( x3), u will get (x3)(3x2) = 0

anonymous

Best ResponseYou've already chosen the best response.0After that make, x3 = 0 and 3x 2 = 0

anonymous

Best ResponseYou've already chosen the best response.0howd you get (x3) and (3x2)

anonymous

Best ResponseYou've already chosen the best response.0from 3x(x+3) 2(x+3) = 0, factorise (x+3)

Best ResponseYou've already chosen the best response.0take out x+3 , then 3x2 is other balance

anonymous

Best ResponseYou've already chosen the best response.0from 3x(x+3) 2(x+3), take out x3, from 1st term 3x and 2nd term 2 is balance

anonymous

Best ResponseYou've already chosen the best response.0because (x+3)(x+3) cancel out. leaving ONE (x+3) and whats left is 3x2?

anonymous

Best ResponseYou've already chosen the best response.03x(x+3) 2(x+3) if u see front of (x+3),there is 3x and 2.

Best ResponseYou've already chosen the best response.0nope, 3x2 = 0 and x+3=0 3x=2 x=3 x=3/2

Best ResponseYou've already chosen the best response.0x = 2/3 is correct, if u substitute in to the function, it will satisfy.
