Question

Which expression shows the sum of the polynomials with like terms grouped together? (8x+3z-8z^2)+(4y-5z)

Answer 1

Answer:

$8x+4y-2z-8z^2$

Step-by-step explanation:

Given

$(8x+3z-8z^2)+(4y-5z)$

Required

Write an expression that shows their sum

$(8x+3z-8z^2)+(4y-5z)$

Open Brackets

$8x+3z-8z^2+4y-5z$

Collect Like Terms

$8x+3z-5z-8z^2+4y$

$8x-2z-8z^2+4y$

Reorder the polynomial

$8x+4y-2z-8z^2$

Hence, $8x+4y-2z-8z^2$ is equivalent to $(8x+3z-8z^2)+(4y-5z)$
