♠️Question:

Find a quadratic polynomial each with the given numbers as the sum and products of its zeros are 2√3-1,3-√3.?

♠️Answer:

Let there be a Quadratic polynomial p(x)

 \large{ \sf{ \alpha  \: and \:  \beta \:  are \: zeroes \: of \: p(x)}}

Then,

 \large{ \sf{ \boxed{ \red{p(x) =  {x}^{2}  - ( \alpha  +  \beta )x +  \alpha  \beta }}}}

Here sum of zeroes= 2root3 -1

And product of zeroes = 3- root3

That means,

 \large{ \sf{ \to \: given \:  \:  \alpha  +  \beta  = 2 \sqrt{3}  - 1}} \\  \large{ \sf{ \to \: and \:  \alpha  \beta  = 3 -  \sqrt{3} }}

Then the required polynomial p(x) is

 \large{ \sf{ \boxed{ \green{{p(x) =  {x}^{2}  - (2 \sqrt{3 }  - 1)x + 3 -\sqrt{3} }}}}}

♠️So final answer:

 \large{ \boxed{ \bold{ \red{ {x}^{2}  - (2 \sqrt{3}  - 1)x + 3 -  \sqrt{3} }}}}
