Question

if f(x)=x^2-x-2 & α and β are zeros of f(x). find the polynomial whose zeros are 2α+1 ,2β+1....
best answer will be marked as brainlist.....

Answer 1

If you take 2 alpha +1
then , alpha= - 1/2
and if you take 2 beta + 1
then beta= -1/2

then alpha+beta= -1/2+-1/2= -1
and alpha* beta= 1/4

then put the values in the formula
x²- (alpha+ beta)x + (alpha * beta )
you can get the polynomial...

I hope it will helpful to you...

Answer 2

Req. polynomial is x^2 - 4x- 5 = 0 .. solution is in the pic :)
