Question 58908: Please help me to solve.
State which method should be applied as the first step for factoring the polynomial.
6x3 + 9x
should I find GCF first, group the terms or use the ac (trial and error) method? thanks for your time.
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
6x^3 + 9x
Determine the "common factor":
The common factor in 6 and 9 is 3
The common factor in x^3 and x is x
So, the common factor is 3x
---------
Rewrite the problem with the common factor separated:
=3x(2x^2+3)
End of story.
Cheers,
