ab increased by 2
2x+3 is an algebra or algebraic expression because an algebraic expression is one or more algebraic terms in a phrase. It can include variables, constants, and operating symbols, such as plus and minus signs. It's only a phrase, not the whole sentence, so it doesn't include an equal sign. so 2xy +3x is an algebraic expression but x+y=2 is NOT.
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.
The variable is d, in the algebraic expression 7d+2
b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.
ab increased by 2
Equation, not expression. A and B are two numbers. (A + B)2 = A2 + B2 + 2(AB) ----------------------------------

x^2 plus 16y?
It is the same as: -2q-3 as an algebraic expression
Algebraic phrase is a mathematical expression which substitutes characters and letters for a certain numeric value. For example a=b+c, if b=2 and c=3, then a=5.
It is simply: 5m+2
