Is equality correct?
To determine if the equation is true, we'll need to expand both sides and compare their forms.
We begin with the left-hand side:
Expanding using the distributive property, we get:
This simplifies to
Further simplification gives
Now, let's examine the right-hand side:
Expanding using the distributive property, we obtain:
This simplifies to
Further simplification yields
Next, compare the results:
The left-hand side is , while the right-hand side is .
Note that the coefficients of the terms are different:
On the left: The coefficient of is .
On the right: The coefficient of is .
Since the coefficients of differ, the two expressions are not equal.
Therefore, the equality is not correct.
The correct answer to this problem is No, the coefficients of in contrasting expressions.
No, the coefficients of In contrasting expressions
\( (3+20)\times(12+4)= \)
You cannot rearrange factors in a product! and are completely different expressions that expand to different polynomials.
Use FOIL method: First terms, Outer terms, Inner terms, Last terms. For example: .
Compare each coefficient separately: the coefficient, the coefficient, and the constant term. All three must match for equality.
Left side: . Right side: . The order of the constants (8 vs -8, -4 vs +4) creates opposite signs!
Only if they're identical after expanding! If any coefficient differs, the expressions are equal only for specific x values, not for all x values.
