Step-by-step explanation:
<span>2a^2+ab+5ab+5b^2
2a(a+b) +5b(a+b)
(a+b)(2a+5b)</span>
Well.. a polynomial expression is an expression that has 3 or more different algebraic terms.
Algebraic terms can be: x^2, 2x, or x^3
One example is: x^2 + x^3 - 7y
Since x^(-2)+5 only has one algebraic term, which is x^(-2), this is not a polynomial.
