Question

Find the sum Adding and Subtracting Polynomials (2n2−5n−6)+(−n2−3n+11)=

Answer 1

EXPLANATION :-

$= (2 {n}^{2} - 5n - 6) + ( - {n}^{2} - 3n + 11)$

$= 2 {n}^{2} - 5n - 6 - {n}^{2} - 3n + 11$

$= 2 {n}^{2} - {n}^{2} - 5n - 3n - 6 + 11$

= (n²-8n+5)→Answer

Answer 2

Collect like terms
2n2 i’m gonna assume is 2n^2
and n2 is 2n
2n^2-10n+5
