Question

Match the following:

• A. Like terms
• B. Unlike terms
• C. Unlike terms

Answer 1

$\underset{–}{-5x^{2}andx12x}$

$x12x$ can be simplified as $12x^2$.

Now, $-5x^2$ and $12x^2$ have the same variable and same corresponding exponents, hence, they are like terms.

$\underset{–}{16p^{3}and-3p^{16}}$

They have same variables but different exponents, hence, are unlike terms.

$\underset{–}{-2a^3{b}^{4}and-4a^3}$

They have different variables as well as different exponents, hence, are unlike terms.
