Question

factorise fully
8mp - 12

Answer 1

8mp - 12 = 4(2mp - 3)

Answer 2

should be 8mp-12=8mp-12
>8mp-8mp=+12-12
>8mp-8mp=0 ,then +12-12=0 i think its right.

Answer 3

i think you've confused factorising with solving equations. when we factorise we want to put something into brackets, like 45 = 9(5)

if theres no equals sign in what you're given, we cant really solve it like you tried to do (i think thats what you're doing)

we are looking for common factors; what is a factor of 8mp AND -12 ? well both can be divided by 4 so what we do is divide them by four and put it outside the bracket:

8mp - 12 = 4(2mp - 3)

Answer 4

do you see what i mean?

Answer 5

ah,i see.
