Example: determine the zeroes of following polynomials.
P ( x)= 5x5 - 20x4+5x3 + 50x2 - 20x - 40 = 5 (x + 1)2 ( x - 2)3
Solution
In this the factoring has been done for us. Do not worries regarding factoring anything like this? You won't be asked to perform any factoring of this type anywhere in this material. There are only here to make the point that the zero factor property works here as well.
In this case we do have a product of 3 terms however the first is a constant and will not make the polynomial zero. So, from the last two terms it looks like the polynomial will be zero for x = -1 and x =2 .Thus, the zeroes of this polynomial are, x = -1 & x = 2
find the average rate of change of the function f(x)=4x from X1=0 to x2=6
I need to do a coursework for math but do not know what to do?
5x + 2y = 6 -2x + y = -6
Solve the following simultaneous equations by using Cramer's rule 3x+2y=13 2x-y=4
Sketch the graph of P ( x ) = 5x 5 - 20x 4 + 5x 3 + 50x2 - 20x - 40 . Solution We set up the zeroes & multiplicities of this polynomial in the previous section hence
a+2+3(2a-1)
