Hey..!!! Pls... Help me.....I am not able to understand Polynomials.....Pls advice how to understand this chapter of maths of Xth.....

Q1. If alpha and beeta are the zeroes of the quadratic polynomials f(x)= x^{2 }-4x +3,find the value of alpha^{4} beeta^{2}

+alpha^{2} beeta^{4}.

Q2. If alpha and beeta are zeroes of the polynomials x^{2}-2x+3, then form a quadratic polynomials whose

zeroes are alpha+2 and beeta+2.

Q3. If alpha and beeta are the zeroes of the quadratic polynomials P(x) =ax^{2}+bx+c,then evaluate:

alpha/beeta+beeta/alpha

PLEASE ANSWER MY QUESTIONS....I AM IN PROBLEM...!!!!

Also αβ=c/a=3/1=3

=α^{4}β^{2}+α^{2}β^{4}

=α^{2}β^{2}(α^{2}+β^{2})

=(3)^{2}[(α+β)^{2}-2αβ] {because w.k.t (a^{2}+b^{2}=(a+b)^{2}-2ab)}

Substituting the values of αβ and α+β

= 9{(4)^{2}-2(3)}

9(16-6)

9(10)

90

2 ans: do the same like the first one answer is x^{2}-8x+11

3 ans: is also similar to the first and second one the answer is (b^{2}-2ca)/ac
