Question

simplify (5xy+3z²)+(2xy-4z²)​

Answer 1

The simplest form of

$5xy-x^2t+2xy+3x^2t5xy−x$

$7xy+2x^2t7xy+2x$

Step-by-step explanation:

We need to simplify the expression

$5xy-x^2t+2xy+3x^2t5xy−x$

For this first take collectively the coefficients of (xy) and (x²t). So,

$\begin{gathered}=(5xy+2xy)+(-x^2t+3x^2t)\\\\=(7xy)+(2x^2t)\\\\=7xy+2x^2t\end{gathered}$

Answer 2

Let's simplify step-by-step.

★$\rm 5xy+3z^2+2xy−4z^2$

★$\rm =5xy+3z^2+2xy+−4z^2$

Combine Like Terms:

★$\rm=5xy+3z^2+2xy+−4z^2$

★$\rm =(5xy+2xy)+(3z^2+−4z^2)$

★$\rm =7xy+−z^2$

Answer:

★$\rm =7xy−z^2$
