Q. Factor out the greatest common factor. If the greatest common factor is 1, just retype the polynomial. 2y2+4y
Determine GCF: Now that we have determined the GCF to be 2y, we can factor it out from each term in the polynomial.The term 2y2 can be written as 2y×y, and the term 4y can be written as 2y×2.So, factoring out the GCF 2y from the polynomial gives us:2y2+4y=2y(y)+2y(2)=2y(y+2).
