Question

are theses right?????
What is the quotient: (2x2 + 6x – 8) ÷ (x + 4) ?

2x – 6

2x + 6

2x – 2 --->MY ANSWER

2x + 2
According to The Fundamental Theorem of Algebra, how many zeros does the function f(x) = 4x5 – 2x – 15 have?

2

3

4

5 --->MY ANSWER

Answer 1

look good

Answer 2

thanks for checking

Answer 3

\[ \frac{2x^2 + 6x – 8}{x+4} = \frac{2(x-1)(x+4)}{(x+4) }= 2(x-1)= 2x-2\]

Answer 4

for the 2nd question, the highest order term (biggest exponent) is 4x^5
that means you have 5 "roots" (though they may be complex or repeated )

Answer 5

thanks :)
