Question

Identify terms which contain x and give the coefficient of x.

(i) y²x + y

(ii) 13y² – 8yx

(iii) x + y + 2

(iv) 5 + z + zx

(v) 1 + x + xy

(vi) 12xy² + 25 — 12xy²

(vii) 7x + xy²

Answer 1

(i) y²x + y

Terms which contains x - y²

co-efficient of x - y²

(ii) 13y² - 8yx

Terms which contains x- (x - 8yx)

co-efficient of x - (-8y)

(iii) x + y + 2

Terms which contains x - x

co-efficient of x -1

(iv) 5 + z + zx

Terms which contains x - x

co-efficient of x - z

(v) 1 + x + xy

Terms which contains x - x and xy

co-efficient of x - 1 y

(vi) 12xy² + 25 - 12xy²

Terms which contains x

co-efficient of x - 12y²

(vii) 7x + xy²

7x Terms which contains x

co-efficient of x - 7

Terms which contains x - xy²

y² co-efficient of
