Step-by-step explanation:

Given,

\sf\alpha,\beta are the zeroes of p(x) = \sf 2x^{2} - 3x + 1

To Find :-

The Quadratic Polynomial whose roots are :-

 \alpha  { \beta }^{2} , { \alpha }^{2}  \beta

Solution :-

To need obtain the roots of the polynomial we need to equate that polynomial to zero :-

2x² - 3x + 1 = 0

2x² - 2x - x + 1 = 0

2x(x - 1) - 1(x - 1) = 0

(x - 1) (2x - 1) = 0

(x - 1) = 0 , (2x - 1) = 0

x = 1 , 2x = 1

x = 1 , x = 1/2

 \alpha  = 1, \beta  =  \dfrac{1}{2}

\sf\alpha(\beta)^{2} = 1\times \left(\dfrac{1}{2}\right)^2

= \sf\dfrac{1}{4}

\sf(\alpha)^{2}\beta = (1)^{2}\times \dfrac{1}{2}

= \sf\dfrac{1}{2}

Required Polynomial :-

\sf x^{2}-\left(\dfrac{1}{4}+\dfrac{1}{2}\right)x + \left(\dfrac{1}{4}\times \dfrac{1}{2}\right) = 0

= \sf x^{2} - \dfrac{3x}{4} + \dfrac{1}{8} = 0

= \sf 8x^{2} - 6x + 1 = 0
