Question

Find by inspection the coefficien
nd by inspection the coefficient of x in the following expansions.
(iii) (x-p) (X-q)
(i) (x + 17) (x + 2)
(ii) (x + 1) (3 - x)
(iv) (2 + 3x) (3 - 5x)
(vi) (px - 1) (px - 1)
(v) (5 - x)(X + 8)​

Answer 1

Answer:

v) (5-x) (x+8)

=5x+40-x²-8x

=40-x²-8x

=-x²-8x+40

Answer 2

Step-by-step explanation:

following expansions.

(iii) (x-p) (X-q)

(i) (x + 17) (x + 2)

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

(iv) (2 + 3x) (3 - 5x)

(vi) (px - 1) (px - 1)

(v) (5 - x)(X + 8)
