Question: Find zeroes of the following polynomials: 1) p(x) = 5x - 3 2) p(x) = x^2 - 2x - 8

Answer 1

Answer:

Let p(x)=x

2

−2x−8

Zero of polunominal is value of x where P (x)=0

Putting p(x)=0

x

2

−2x−8=0

We find roots using splitting the middle e term method

] Here, we need two term where sum=−2 product =−8×1=−8

x

2

−4x+2x−8=0

x(x−4)+2(x−4)=0

(x+2)(x−4)

So x=−2,4

Therefore , α=−2 & β=4 or zero of polunominal
