(5 −3)( +2)^2​

Answer 1

Answer:

mark me and check my profile

Step-by-step explanation:

(2+x)5=32+80x+80x2+40x3+10x4+x5 Therefore the coefficient of x2 in the expansion of (2+x)5 is 80.

Answer 2

2+x)5=32+80x+80x2+40x3+10x4+x5 Therefore the coefficient of x2 in the expansion of (2+x)5 is 80......
