Answer:
1) Quartic (if asking about degree)
2) 2 terms
3) 8
4) 3x^4
5) 3
Step-by-step explanation:
1) since the degree of the polynomial is 4, it is classified as a quartic polynomial.
2) there are 2 terms (it's a binomial)
3) constant term is the term in a polynomial without a variable, in this case 8
4) leading term is the term with the highest degree throughout the whole polynomial, in this case it is 3x^4
5) leading coefficient is the coefficient to the term with the highest degree, in this case this would be regarding the term 3x^4, meanign the coefficient is the 3
It's totally okay to be confused! u got this mate :D
Answer:
(x - 7)(x - 4)(x + 4).
Step-by-step explanation:
A(x) = x3 – 7x² – 16x +112
Dividing by x-7:
x^2 - 16 <-------- Quotient
-----------------------------
x-7)x^3 - 7x^2 - 16x + 112
x^3 - 7x^2
0 - 16x + 112
- 16x + 112
..............
so A(x) = (x - 7)(x^2 - 16) x^2 - 16 is the difference of 2 squares so we have:
(x - 7)(x - 4)(x + 4).
Checking by expanding the brackets:
(x - 7)(x - 4)(x + 4)
= x(x - 4)(x + 4) - 7(x - 4)(x + 4)
= x(x^2 - 16) - 7(x^2 - 16)
= x^3 - 16x - 7x^2 + 114
= x^3 - 7x^2 - 16x + 112
Answer:
I don't know where those choices are from but the answer is -21.....
Step-by-step explanation:
24 − (23 + 22)
24-23-22
-21
