Question

* Find the zeroes of the following polynomials by factorisation method
and verify the relations between the seas and the co-effecients
of the polynomial
(1.) p(x) = 4x^2 -3x - 1​

Answer 1

Step-by-step explanation:

4x²-3x-1=0

=>4x²-4x+1x-1=0

=>4x(x-1)+1(x-1)

=>(4x-1)(x-1)

so the zeroes of polynomial 4x²-3x-1 is

(4x-1) =0

=>4x=0

=>x=0/4

=>x=0

also, (x-1) =0

=>x=1

therefore the zeroes of polynomial 4x²-3x-1 is 0 and 1
