Common factors of the first two terms in the expression 5xy + 4ax + 6pa + 8px are:
x, y, a
5, x, y, 4, a
x
y, a
First two terms are 5xy and 4ax 5xy = 5×x×y 4ax = 4×a×x So, the common factor is x.
Find the greatest common factor of the terms in each of the following expressions:
2xyz+3x2y+4y2
(i) Identify the terms and their factors in the following expressions
Show the terms and factors by tree diagrams.
(a) x − 3 (b) 1 + x + x2 (c) y − y3
(d) (e) − ab + 2b2 − 3a2
(ii) Identify terms and factors in the expressions given below:
(a) − 4x + 5 (b) − 4x + 5y (c) 5y + 3y2
(d) (e) pq + q
(f) 1.2 ab − 2.4 b + 3.6 a (g)
(h) 0.1p2 + 0.2 q2
