find: $(4x^{2}y^{3}+2xy^{2}-2y)-(-7x^{2}y^{3}+6xy^{2}-2y)$ place the correct coefficients in the difference. $\\square x^{2}y^{3}+\\square xy^{2}+\\square y$
Answer
Explanation:
Step1: Distribute the negative sign
$(4x^{2}y^{3}+2xy^{2}-2y)-(-7x^{2}y^{3}+6xy^{2}-2y)=4x^{2}y^{3}+2xy^{2}-2y + 7x^{2}y^{3}-6xy^{2}+2y$
Step2: Combine like - terms for $x^{2}y^{3}$
$(4x^{2}y^{3}+7x^{2}y^{3})+(2xy^{2}-6xy^{2})+(-2y + 2y)=(4 + 7)x^{2}y^{3}+(2-6)xy^{2}+(-2 + 2)y$ $=11x^{2}y^{3}-4xy^{2}+0y$
Answer:
$11x^{2}y^{3}-4xy^{2}+0y$
