Question

Find the inspection the coefficient of x in the following expansions
1. (x+17) (x+2)
2. (x+1) (3-x) ​

Answer 1

Answer:

Co-efficient of x = 19

Step-by-step explanation:

the coefficient of x'= -1

the coefficient of x= 2

Step-by-step explanation:

(x + 1) (3 - x)

x(3-x)+1(3-x)

3x-x2+3-x

-x²+2x+3

the coefficient of x2= -1

the coefficient of x= 2
