Answer:
Factor by grouping
Step-by-step explanation:
We are given that a polynomial has four terms
\(3x^3+5x+6x^2+10\)
We have to find which factoring method can be used .
The given polynomial is cubic.
Rearrange the terms then, we get
\(3x^3+6x^2+5x+10\)
\(3x^2(x+2)+5(x+2)\)
\((x+2)(3x^2+5)\)
The method which used there is factor by grouping.
