Find the number of possible negative real zeros for f(x) = x3 – 4x2 – 3x – 9.



Use the Remainder Theorem to find the remainder when 2x3 + 6x2 + 3x – 1 is divided by x – 1. State whether the binomial is a factor of the polynomial.




Approximate the real zeros of f(x) = x3 – 5x2 + 2 to the nearest tenth.

Find the number of possible negative real zeros for f(x) = x^3 – 4x^2 – 3x – 9.
FIND f(-x) = - x^3 - 4x^2 + 3x - 9.......Now count how many times the signs change
....................................1.…

ANSWER..... 2 or (2 - 0) = 0

ANSWER......2...or....0......Number of Negative Roots


Use the Remainder Theorem to find the remainder when 2x^3 + 6x^2 + 3x – 1 is divided by x – 1. State whether the binomial is a factor of the polynomial....WILL BE A FACTOR IF Remainder is ZERO.

If factor is (x - 1) the x = 1................Set x - 1 = 0 and solve

Replace x with 1.........2x^3 + 6x^2 + 3x – 1.....2(1)^3 + 6(1)^2 +3(1) - 1.....2+6+3-1 = 10

ANSWER.........10............Is the Remainder
ANSWER.........NO...........x - 1 Not a factor


Approximate the real zeros of f(x) = x^3 – 5x^2 + 2 to the nearest tenth.

Type function into a graphing calculator. Graph. Use 2nd Trace (Calc) # 2 ZERO

ANSWERS......-0.5977352.........0.6804…

I tutor free online since moving to France from Florida in June 2011.
Hope this is most helpful and you will continue to allow me to tutor you.
If you dont fully understand or have a question PLEASE let me know
how to contact you so you can then contact me directly with any math questions.
If you need me for future tutoring I am not allowed to give out my
info but what you tell me on ***how to contact you*** is up to you
Been a pleasure to serve you Please call again
