Detailed explanation-1: -7x and 2x are like terms because they are both “x". 3x2 and −2x2 are like terms because they are both “x2". But 7x and 7x2 are NOT like terms (the exponents are different), they are unlike terms. Like terms can be added together.
Detailed explanation-2: -Examples of like terms in math are x, 4x, -2x, and 7x. These are like terms because they all contain the same variable, x. The terms 8y2, y2, and-2y2 are like terms as well.
Detailed explanation-3: -Answer: The terms which have the same algebraic factors are called like terms. However, when the terms have different algebraic factors, these are called unlike terms. (i) 1, 100.
Detailed explanation-4: -What are Like Terms? Like terms contain the same variable which is raised to the same power. For example, 5x + 10x is an algebraic expression with like terms. When we have to simplify this algebraic expression, we can add the like terms.
