Question

If alpha and beta are the roots of the equation X square minus 1 is equal to zero then form an equation whose roots are 2 alpha and beta 2 Beta p***

Answer 1

$x^2 - 1 = 0$
x=1 or x= -1
alpha is 1 and beta is -1
2 and -2 are the roots of recquired equation
equation will be x^2 -(2-2) + 2*-2
= x^2 -4
