Question

(5xy^2 + 3x^2y - 2y^2) - ( -7x^2y - 6xy^2 + y^2) simplify

Answer 1

@SolomonZelman

Answer 2

\(\large\color{black}{ (5xy^2 + 3x^2y - 2y^2)- ( -7x^2y - 6xy^2 + y^2) }\)

Answer 3

lets do this,
\(\large\color{black}{ 5xy^2 + 3x^2y - 2y^2- ( -7x^2y) - (-6xy^2) -( y^2) }\) .
Do you agree with what I have done here?

Answer 4

Yes

Answer 5

So, now simplify the parts I"ll label in red.
\(\large\color{black}{ 5xy^2 + 3x^2y - 2y^2\color{red}{- -}7x^2y \color{red}{- -}6xy^2 \color{black}{- }y^2 }\).

Answer 6

the 2 negatives, become what?
(re-write the equation, now)

Answer 7

positive

Answer 8

yes, so it becomes, \(\large\color{black}{ 5xy^2 + 3x^2y - 2y^2\color{red}{+}7x^2y \color{red}{+}6xy^2 \color{black}{- }y^2 }\)

Answer 9

Then combine like terms

Answer 10

And then, the like terms, are

\(\large\color{black}{ \color{blue}{5xy^2} \color{red}{+ 3x^2y} \color{green}{- 2y^2} \color{red}{+7x^2y} \color{blue}{+6xy^2} \color{green}{-y^2} }\)

Answer 11

Sorry it took long to color them.

Answer 12

11xy^2 + 10x^2y + 2y^2?

Answer 13

\(\large\color{black}{ \color{blue}{11xy^2} \color{red}{+ 10x^2y} \color{green}{- 2y^2} \color{green}{-y^2} }\)

Answer 14

one term has an incorrect coefficient.

Answer 15

\(\large\color{black}{ \color{green}{- 2y^2} \color{green}{-y^2} \ne2y^2}\) right?

Answer 16

Yes didnt i have that

Answer 17

you said that the ;ast term is +2y^2, when it is -3y^2.
