Are the expressions the same or not?
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: Simplify the expressions
First expression:
Second expression:
Step 2: Compare the simplified expressions
After simplification:
The first expression is .
The second expression is .
Clearly, these simplified expressions are not the same.
Therefore, the solution to the problem is No.
No
Are the expressions the same or not?
\( 3+3+3+3 \)
\( 3\times4 \)
Like terms have the same variable part! In , both terms have 'x' so they combine. Constants like and are also like terms.
That's exactly why we simplify first! looks nothing like , but after combining like terms, we can see they're actually different.
Not necessarily, but it helps! Writing variables first, then constants (like ) makes it easier to compare with other expressions.
Two expressions are the same if they simplify to identical forms. Even if they look different at first, if they reduce to the exact same coefficients and constants, they're equivalent.
You could try substituting values for x, but that's not a complete proof! Two different expressions might give the same result for some values of x but not others. Algebraic simplification is more reliable.
