Question

Identify, in the following expressions, terms which are not constants. Give their numerical coefficients: (i) xy + 4 (ii) 13 - y

2

(iii) 13 – y + 5y2

(iv) 4p2

q

- 3pq2

+ 5

Answer 1

x , y are not coefficient,

Answer 2

I) xy is not constant. numerical coefficient is 1
2)y^2 is not constant. numerical coefficient is -1
3)y and 5y^2 are not constants.numerical coefficients are -1 and 5
4)4p^2q and 3pq^2 are not constants. numerical coefficients are4 and -3.
