Question

4z⁴-7z³+2z-5z²+3 and 3z²+4z³-2z⁴-z-5​

Answer 1

Answer:

$2 {z}^{4} - 3 {z}^{3} - 2 {z}^{2} + z - 2$

Step-by-step explanation:

Given:

Two expressions.

1. 4z⁴-7z³+2z-5z²+3
2. 3z²+4z³-2z⁴-z-5

To find:

Sum of both expressions

Answer:

$4z^{4}-2 {z}^{4} - 7z^{3} + 4 {z}^{3} -5z^{2}+ 3z^{2} + 2z-z-5 + 3 \\ 2z^{4} -3z ^{3}-2z^{2} +z - 2 \: \sf{ is \: the \: right \: answer} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$
