Identify GCF: Identify the greatest common factor (GCF) of the two terms in the expression 13y3z2−14x3y7z3. The GCF is the product of the lowest powers of common factors in both terms. Both terms have a y and a z factor. The GCF is y3z2 because y3 is the lower power of y (compared to y7) and z2 is the lower power of z (compared to z3).
Factor Out GCF: Factor out the GCF from the expression.We write the expression as y3z2 times the remaining factors.13y3z2−14x3y7z3=y3z2(13−14x3y4z).
Simplify Inside Parentheses: Simplify the expression inside the parentheses.We need to subtract the exponents of y and z from the second term because we factored them out.13y3z2−14x3y7z3=y3z2(13−14x3y4z).The second term inside the parentheses simplifies to 14x3y4z because y7/y3=y4 and z3/z2=z.
Write Final Factored Expression: Write the final factored expression.The completely factored form of the expression is y3z2(13−14x3y4z).
