Question

combine like terms: 3xy-4/5 x^2y -2/9 xy+8/5 x^2y

Answer 1

sorry these ones really confuse me :[

Answer 2

what is the question?

Answer 3

^2 means exponents 2

Answer 4

"Like terms" means that the terms have to have the same variables and the same exponents. For example,
\( 3x\) and \( 5x\) are like terms, but \(3x\) and \(3x^2\) are not.

Answer 5

The same applies to multiple variables:

\(3xy\) and \(5xy\) are like terms, but \(3xy\) and \(5xy^2\) are not

Answer 6

\[\large 3xy-\frac{4}{5}x^2y-\frac{2}{9}xy+\frac{8}{5}x^2y\]

\(\large 3xy\) and \(\large \frac{8}{5} xy\) are like terms and \(\large \frac{4}{5}x^2y\) and \(\large \frac{8}{5}x^2y\) are like terms

Answer 7

sorry \(\large 3xy\) and \(\large \frac{2}{9} xy\) are like terms

Answer 8

So what should happen when you combine the xy like terms?
\[\large \color{red}{3xy}-\frac{4}{5}x^2y\color{red}{-\frac{2}{9}xy}+\frac{8}{5}x^2y\]
