Question

a^2 +ac +ba +bc over a-b ÷ a-b

Answer 1

does it help to know that \((a-b)\div (a-b)=1\)?

Answer 2

It is supposed to say a^2 +ac +ba +bc over a-b ÷ a-c. My fault

Answer 3

Is this the problem?

\(\large \dfrac{a^2 + ac + ba + bc}{\frac{a-b}{a-c} }\)

Answer 4

If so, remember that dividing by a fraction is the same as multiplying by its reciprocal.
Also, since the numerator has four terms, try factoring it by grouping.

Answer 5

No, but how did you do the big fraction bar?

Answer 6

\dfrac is a big fraction bar
\frac is a small fraction bar

Answer 7
