Question

(4x2y3 + 2xy2 – 2y) – (–7x2y3 + 6xy2 – 2y) i need help solving

Answer 1

Answer:

$\huge \boxed{11x^2 y^3-4xy^2 }$

Step-by-step explanation:

$(4x^2y^3 + 2xy^2 - 2y) - (-7x^2 y^3 + 6xy^2 -2y)$

Distribute the negative sign to the terms in the bracket.

$(4x^2y^3 + 2xy^2 - 2y) +7x^2 y^3 - 6xy^2 +2y$

Grouping like terms.

$(4x^2y^3 +7x^2 y^3) + (2xy^2 - 6xy^2 ) +( - 2y +2y)$

Combining like terms.

$(11x^2 y^3) + (-4xy^2 ) +(0)$

$11x^2 y^3-4xy^2$
