Answer:
Error of Andrew: Made incorrect factors from the roots
Step-by-step explanation:
Roots of the polynomial are: 3, 2 + 2i, 2 - 2i. According to the factor theorem, if a is a root of the polynomial P(x), then (x - a) is a factor of P(x). According to this definition:
(x - 3) , (x - (2 + 2i)) , (x - (2 - 2i)) are factors of the required polynomial.
Simplifying the brackets, we get:
(x - 3), (x - 2 - 2i), (x - 2 + 2i) are factors of the required polynomial.
This is the step where Andrew made the error. The factors will always be of the form (x - a) , not (x + a). Andrew wrote the complex factors in form of (x + a) which resulted in the wrong answer.
So, the polynomial would be:
Answer:
the answer is 4
Step-by-step explanation:
2x-2 =4x-10
2x-4x = -10-2
-2x = -8
x = -8/-2
x =4
Answer:
53
Step-by-step explanation:
65x- 12 = 43x + 10
65x - 43x = 10 + 12
22x = 22
x = 22/22
<u>x = 1 </u>
(65x- 12) =
65 * 1 - 12 =<u> 53</u>
43x + 10
43 * 1 -12 = <u>53</u>
First lets do the addition. f(x) + g(x)f(x) + g(x)
2x-1 + 2x + 4
4x -1 + 4
4x + 3
Largest coefficient on x = 4Second lets do the subtraction. f(x) - g(x)f(x) - g(x)
(2x-1) - (2x+4)
2x - 2x - 1 - 4
-5
Largest coefficient on x = 0Third lets do the multiplication. f(x) *g(x)(2x-1) * (2x+4)
Largest coefficient on x = 6
Answer: Multiplication will result in the largest coefficient on the x term.
