Question

11. Obtain all the zeroes of the polynomial
p(x) = x4 - 8x + 23x? - 28x + 12 if two of its zeroes are 1, 2​

Answer 1

Answer:

first do alpha+ beta then do alpha × beta t . alpha and beta are given zeroes

then do

k(x²+alpha×beta - alpha + beta )

Step-by-step explanation:

then you get a quadratic equation then you divide p(x) and quadratic equation u get at last quoetient should be factorised then u get the ans u will obtain other two zeroes
