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
16x-10y=10 -8x-6y=6
4(x)^2-40x+107 in standard form
Process for Finding Rational Zeroes 1. Utilizes the rational root theorem to list all possible rational zeroes of the polynomial P ( x ) 2. Evaluate the polynomial at the nu
In this section we are going to look at equations which are called quadratic in form or reducible to quadratic in form . What it means is that we will be looking at equations th
