Answer 2

Answer:

We can Split the Middle Term of this expression to factorise it

In this technique, if we have to factorise an expression like ax2+bx+c , we need to think of 2 numbers such that:

N1⋅N2=a⋅c=8⋅9=72

AND N1+N2=b=18

After trying out a few numbers we get N1=12 and N2=6

12⋅6=72 , and 12+6=18

8x2+18x+9

=8x2+12x+6x+9

=4x(2x+3)+3(2x+3)2x+3

is a common factor to each of the terms

=(2x+3)(4x+3)
