Q. Factor completely.\newline13y3z214x3y7z3 13 y^{3} z^{2}-14 x^{3} y^{7} z^{3} \newlineAnswer:
  1. Identify GCF: Identify the greatest common factor (GCF) of the two terms in the expression 13y3z214x3y7z313y^{3}z^{2}-14x^{3}y^{7}z^{3}. The GCF is the product of the lowest powers of common factors in both terms. Both terms have a yy and a zz factor. The GCF is y3z2y^{3}z^{2} because y3y^{3} is the lower power of yy (compared to y7y^{7}) and z2z^{2} is the lower power of zz (compared to z3z^{3}).
  2. Factor Out GCF: Factor out the GCF from the expression.\newlineWe write the expression as y3z2y^{3}z^{2} times the remaining factors.\newline13y3z214x3y7z3=y3z2(1314x3y4z)13y^{3}z^{2}-14x^{3}y^{7}z^{3} = y^{3}z^{2}(13 - 14x^{3}y^{4}z).
  3. Simplify Inside Parentheses: Simplify the expression inside the parentheses.\newlineWe need to subtract the exponents of yy and zz from the second term because we factored them out.\newline13y3z214x3y7z3=y3z2(1314x3y4z)13y^{3}z^{2}-14x^{3}y^{7}z^{3} = y^{3}z^{2}(13 - 14x^{3}y^{4}z).\newlineThe second term inside the parentheses simplifies to 14x3y4z14x^{3}y^{4}z because y7/y3=y4y^{7}/y^{3} = y^{4} and z3/z2=zz^{3}/z^{2} = z.
  4. Write Final Factored Expression: Write the final factored expression.\newlineThe completely factored form of the expression is y3z2(1314x3y4z)y^{3}z^{2}(13 - 14x^{3}y^{4}z).
