how do i factorise this question???

Question

ab+abc=

for instance 2p+6xp=2p(1+3x)

mischavee i own a scientific calculator

i think the answers ab(1+c)

Answer 1

To factorise the expression, note what is common between the 2 terms. In this case both terms have the variable ab, so you can factorise out ab.

ab+abc=ab(1+c)

Note that the 1 is necessary as without the 1, ie. ab(0+c), when you expand that to check, you only get abc and the ab term has been omitted. Thus a gd practice would be to check your factorisation by expanding it out again to obtain the initial terms, to see if you did it correctly.

Answer 2

Look for a number that is present in both terms.
This number is ab and ab is then the common factor.
ab + abc = ab(1 + c)
Check
ab x 1 + abc = ab + abc

Answer 3

you are right on both accounts

ab+abc=ab(1+c)
2p+6xp=2p(1+3x)

Answer 4

get a life and leave me alone
