Question

find the sum of the following polynomial and write the degree of the sum obtained 3x2+5x+x7; -3x2+5x+8​

Answer 1

Answer:

The sume is $10x+15$ and degree is 1

Step-by-step explanation:

Required sum

$=(3x^2+5x+7)+(-3x^2+5x+8)\\=3x^2+5x+7-3x^2+5x+8\\=10x+15$

And degree of sum $=$ Highest power of $x$ $=1$
