Resolve the following into factor ab+ac-ad

  a(b+c-d)

Step-by-step explanation:

Each term has a factor of "a", so that can be factored out. The remaining factor cannot be factored any further.

  ab +ac -ad = a(b +c -d)

a(b + c - d)

Step-by-step explanation:

'a' is common to all three terms of the given expression.  Thus, the expression in factored form is a(b + c - d).

the answer is d
