Question

Plz solve 5th question given in attachment .i will definately mark uuh as brainlest for proper answer.

Answer 1

Answer:

First u have to factorise

x²-4x+3

x²-x-3x+3

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

(x-1)(x-3)

x-1=0

x=1

α=1

x-3=0

x=3

β=3

Now, roots/zeroes of 3α and 3β

So,

Put value of alpha and beeta

3*1  and   3*3

3 and 9

Sum of zeroes= 3+9 = 12

Product of zeroes = 3*9 = 27

Q.P. = x²-(sum of zeroes)x + (product of zeroes)

       = x²-12x+27

Quadratic polynomial is x²-12x+27
