Question

Group the like terms together:
12x, 12a, 25p, -25, 25q, 1, x

OPTIONS

A. 12x, x
B. 12a, 12x
C. 25p, -25, 25q
D. 12a, 25q

Answer 1

$\huge{\underline{\underline{\boxed{\boxed{\mathfrak{\red{Hi \:Dear}}}}}}}$

$\large{\boxed{\red{\boxed{\mathfrak{\pink{Answer}}}}}}$

A. 12x, x ✔️

The terms which have the same variable raised to the same power but may only differ in numerical coefficient are called like terms.

For example:

(i) 3m and -7m are like terms.

(ii) z and $\frac{3}{2}$z are like terms.

So, in the given set of terms, 12x and x are like terms.

Answer 2

Group the like terms together:

12x, 12a, 25p, -25, 25q, 1, x

OPTIONS

A. 12x, x

B. 12a, 12x

C. 25p, -25, 25q

D. 12a, 25q

Solution :-

Like Terms are those terms whose have same power of degree , every term have same degree of the same variable ..

→ in option B , 12a ans 12x are different variables .

→ in option C also , 25p, -25, 25 q are different variables.

→ in option D also , 12a and 25p are different variables..

→ in Option A 12x and x have same degree 1 and same variable x

Hence, out right answer is OPTION A.
