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
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
b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.
ab increased by 2
(a-b)(a^2 + ab + b^2)
Equation, not expression. A and B are two numbers. (A + B)2 = A2 + B2 + 2(AB) ----------------------------------

b2 + ab - 2 - 2b2 + 2ab = -b2 + ab - 2 which cannot be simplified further.
It is the same as: -2q-3 as an algebraic expression
x^2 plus 16y?
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
