Find the Quadratic polynomial whose sum and product of zeros are √2+1 ,1/(√2+1)

√2 x²+2x-1
x²-2√2 x+1
x²-2x+√2
√2 x²-2x+1

Answer 1

Answer:

According to me the answer to the first one should be d)

the answer to the second one is:-

x/y+y/x=-1

x^2+y^2=-x*y

x^3-y^3=(x-y)(x^2+y^2+xy)

x^3-y^3=(x-y)(0)

x^3-y^3=0

the answer to the third question is:-

25x^2-1+1+5x^2

25x^2+5x^2

30x^2

3x(10x)

therefore =d)
