Question

factorise p(x) = x² - 4x + 3 , find the zeroes of the polynomial and compare with their coefficients​

Answer 1

Answer:

x²-4x+3

=x²-3x-x+3

=x(x-3)-1(x-3)

x-1=0

x=1

x-3=0

x=3

When f(1)

       ∴   1²-4(1)+3

          =   1-4+3

           =   4-4

               = 0

When f(3)

       ∴    3²-4(3)+3

            =  9-12+3

            =   12-12

               =  0
