Answer:
Explanation:
Solution 1
The easy way is to compare the leading terms or constants.
LHS
The leading term is:
The constant is:
RHS
The leading term is:
The constant is:
We see both the leading terms (10x³ ≠ 15x³) and constants (-18 ≠ -12) are different so the equation is false.
Solution 2
We see one of the factors is same on both sides:
The other factors are:
Since this factor is different on both sides, the equation is false
