Question

Factories fully the following
a)2x+8
b)3x-12
c)6x+4
d)18x-9

Answer 1

a) 2(x + 4)

b) 3(x -4)

c) 2(3x + 2)

d) 9(2x - 1)

Explanation:

a) Factor: 2x+8

2x + 8

= 2(x + 4)

b) Factor 3x−12

3x − 12

= 3(x − 4)

c) Factor 6x+4

6x + 4

= 2(3x + 2)

d) Factor 18x−9

18x − 9

= 9(2x − 1)

Answer 2

a) 2(x+4)

b) 3(x-4)

c) 2(3x+2)

d) 9(2x-1)

Explanation:

a) 2x+8=2(x+(8/2))=2(x+4)

b) 3x-12=3(x-(12/3))=3(x-4)

c) 6x+4=2((6/2)x+(4/2))=2(3x+2)

d) 18x-9=9((18/9)x-(9/9))=9(2x-1)
