Question

Group the like terms from the following algebraic terms:

$20y,20a^2,15q,-25s,25a,12z,y$

• A. $20y,y$
• B. $-25,25a$
• C. $15q,12z$
• D. $20y,20a^2$

Answer 1

The correct option is A

$20y,y$

Like terms are those terms which contain the same variable raised to the same power.

$20y,20,15q,-25s,25a,12z,y$

In the above terms $20y$ and $y$ have same variable $y$ and the exponent of the variable $y$ is 1.

$\therefore 20y$ and $y$ are like terms.
