Question

Can you explain why the problem below is solved the way it is?

Answer 1

\[2b ^{2}+7b+3\]
\[2b ^{2}+1b+6b+3\]
\[b(2b+1)+3(2b+1)\]
\[(b+3)(2b+1)\]

Answer 2

I don't understand the second step. Why is \[7b\] split into \[1b\] and \[6b\]?

Answer 3

multiply b^2 's coefficient with last term
wt do u get?

Answer 4

What..?

Answer 5

u know b^2's coefficient ?

Answer 6

coefficient means numerical value attached with variable

Answer 7

so wt is coefficient of b^2

Answer 8

tell me
