Math Problem Statement
given the polynomial p(x) = -3x^4 + 2x^3 -7^6 +x^5, which of the following is FALSE? a) the constant term of p(x) is -117649 b) the degree of p(x) is 5 c) the leading coefficient of p(x) is -7
Solution
Let's analyze the polynomial .
Step-by-step breakdown:
-
Simplify the polynomial: Notice that is just a constant, which equals , so: Rearranging the terms:
-
Examine each statement:
a) Constant term: The constant term is , which matches statement a. Thus, this is true.
b) Degree of the polynomial: The highest power of is (from ), so the degree of the polynomial is . Statement b is also true.
c) Leading coefficient: The leading term is the one with the highest degree, which is . The coefficient of this term is (not ), so statement c is false.
Conclusion:
The false statement is c) the leading coefficient of is -7.
