Identify common factors: Identify common factors in the terms.Both terms x4 and 7x3 have a common factor of x3.
Factor out GCF: Factor out the greatest common factor (GCF).The GCF of x4 and 7x3 is x3. So we factor x3 out of the expression.x4+7x3=x3(x+7)
Check for further factoring: Check to see if the factored expression can be factored further.The expression inside the parentheses, x+7, cannot be factored further since it is a sum of a variable and a constant.
