Question

Which expression(s) below can best be factored by grouping?


There may be more than one correct answer. Be sure to select all that apply.

Answer 1

(3x+4)(3x-4) for the last one which is the difference of two squares. I think
Top one looks promising ...
BOTH are quadratics and that makes it slightly less "intimidating", shall we say.

Answer 2

May I help?

Answer 3

please do

Answer 4

With my pleasure!

Of course you know how to factor by grouping!

Answer 5

right!

Answer 6

Great!
What do you think about the second one?

Answer 7

i think not

Answer 8

What about that?
\[8x^3+4x^2-10x-5=(8x^3+4x^2)-(10x+5)=4x^2(2x+1)-5(2x+1)\]
\[=4x^2(2x+1)-5(2x+1)=(2x+1)(4x^2-5)\]

Looks nice!?
