Answer 1

factorize the above term

Answer 2

how?

Answer 3

@nnnnnns please help!

Answer 4

@jim_thompson5910 please help!

Answer 5

factor the numerator to get


3b^2+13b+4


3b^2+b+12b+4


(3b^2+b)+(12b+4)


b(3b+1)+(12b+4)


b(3b+1)+4(3b+1)


I'll let you finish factoring

Answer 6

wait what?

Answer 7

What I did was multiply 3 and 4 (first coefficient and last term) to get 3*4 = 12

Then I found two numbers that multiply to 12 (the previous result) and add to 13 (middle coefficient)

the two numbers are 1 and 12, so you break 13b into 1b+12b or b+12b

from there you factor by grouping

Answer 8

ok then what?

Answer 9

b(3b+1)+4(3b+1)

would turn into what when you factor it

Answer 10

ok, but how do you find the undefined value @jim_thompson5910 ?
