Answer:
X = 6
Step-by-step explanation:
17 - 5 = 12
12 ÷ 2 = x
12 ÷ 12 = 6
If
then complex number
is a root of cubic polynomial.
If polynomial has real coefficients, then conjugated
is also a root of polynomial.
Then the polynomial will be of a form

Since
then

Therefore,

Draw up a right triangle to connect these two points with the line itself being the hypotenuse. Then use pythagorean theorem to solve for the hypotenuse
7x^5-33x^4-4x^2+3x+52=
ANSWER: 7x^5 -33x^4 -4x^2+3x+52 (because there are no like terms)
