All of the following are equivalent, except 2 x²
Option D is correct.
Step-by-step explanation:
We need to find equivalent equations.
Considering 2 x + x , x(2 + 1),3 x ,2 x² as 3 options I am solving this question.
The terms are equivalent, if after simplifying they gave the same result.
1) 2 x + x
Adding like terms:
2 x + x
= 3x
2) x(2+1)
Adding terms inside the bracket:
x(2+1)
=x(3)
Multiply x with the terms inside the bracket
=3x
3) 3 x
It cannot be further simplified.
4) 2x^2
It cannot be further simplified.
So, equivalent terms are 2x+x , x(2+1) and 3x because after simplifying we get the same answer i.e 3x
while 2 x² is not equivalent because after simplifying we get 2x^2
All of the following are equivalent, except 2 x²
Option D is correct.
