 Question 378717: Please solve. Are (x+4) and (x+1) factors of the polynomial (x^3 - 13x + 12)? dsingletary@fsd1.orgFound 2 solutions by jim_thompson5910, Alan3354:Answer by jim_thompson5910(28504)   (Show Source): You can put this solution on YOUR website!To see if (x+4) is a factor, use polynomial long division to find that Since we get a remainder of 0, this means that (x+4) is indeed a factor. To see if (x+1) is a factor, use polynomial division again to get This time we don't get a remainder of 0. So (x+1) is NOT a factor.
