Factorise ac-3+3x-a
Is there a possible solution for this?

Thanks

e^(i*pi)
There is no factor common to the who equation but you can factor into two terms

\$\displaystyle a(c-1) - 3(1-x)\$

Prove It
If you meant \$\displaystyle \displaystyle ac - 3 + 3c - a\$

\$\displaystyle \displaystyle = ac - a + 3c - 3\$

\$\displaystyle \displaystyle = a(c - 1) + 3(c - 1)\$

\$\displaystyle \displaystyle = (c-1)(a+3)\$.
