Identify GCF: Identify the greatest common factor (GCF) of the two terms.The GCF of 45 and 27 is 9. The GCF of x5 and x4 is x4. The GCF of y6 and y4 is y4. There is no z term in the first expression, so 270 is not part of the GCF.
Factor out GCF: Factor out the GCF from the original expression.The GCF is 9x4y4, so we factor this out from each term.45x5y6+27x4y4z3=9x4y4(5x5−4y6−4+3z3)
Simplify inside parentheses: Simplify the expression inside the parentheses.Subtract the exponents for x and y in the first term inside the parentheses since we factored out x4 and y4.5x(5−4)y(6−4)+3z3=5x1y2+3z3
Write final factored expression: Write the final factored expression.The completely factored form is 9x4y4(5xy2+3z3).
