Question

if alpha and beta are the zeroes of polynomial x^2-4x+3 then, find the quadratic polynomial whose roots are 3alpha and 3 beta

Answer 1

Instead of alpha I am taking m and instead of beta I am using n sorry...
m+n=-b/a
m+n=4/1=4
m×n=c/a
m×n=3/1=3
The root are 3 and 4
By this method you can find
