How do you solve a plus ab?

Answer 1

What is it you want to solve? You can factor it, taking out the common factor, "a". Thus, a + ab = a(1 + b). Or, if you want to convert it to a number, you can only do this if you know the values for "a" and "b". In this case, replace the values, and do the calculation.

Answer 2

Plus ab is an algebraic expression.

As given you cannot solve it.

However,

If you have

x +ab = c

Then 'ab' can be solved.

We do this by subtracting 'x' from both sides. (Preserve equality)

x - x + ab = c - x

x-x = 0 , just like 2 - 2 = 0

Hence

ab = c -x
