ab + 2
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.
The variable is d, in the algebraic expression 7d+2
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.
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
