Ab - ac = a(b-c)?

Question

true or false

Answer 1

when u r solving this problem u should focus on the a. the reason ab-ac=a(b-c) is because u use distributive proberty on the (b - c) to get ab - ac, because a * b= ab  and a * c = ac

therefore a distributed to ( b-c) equals ab-ac. pretty good for a 9th grader huh lol. hope i helped: )

Answer 2

ture

a(b-c)= ab-ac so ab-ac = ab-ac

Answer 3

Indeed it does, True. Basic factors.

Answer 4

Yes it is equal

Answer 5

Short answer: in 'normal' maths, this is always true.

Longer answer: that's the axiom of left distributivity, which holds for all rings. So it's always true when a, b, c are, for instance, real numbers.

-edit- to those who say "A isn't necessarily equal to a": that's just Yahoo! Answers capitalizing the first letter of the sentence, just like it adds a question mark when it seems to be missing. When you try to answer the question, you might notice that the question is all lowercase, just the way the QP wrote it.

Answer 6

true

ex(1x3-1x2)=1

   1(3-2)=1

Answer 7

true

But in the question form it is written as Ab - ac = a( b-c )

that is wrong

Answer 8

false..

because there are different values for every capital letters and Small letters in algebra..

Answer 9

True, I don't see anything wrong with that conclusion but it matters on the topic at hand.

could obviously be a(b+-c) but no point in that

Answer 10

False.

Because "A" is not equal to "a".
