Question

If alpha and beta are the zeroes of the quadratic polynomial f(x)=ax2 +bx +c,then evaluate 1/a×alpha+ b 1/a× beta+ b

Answer 1

Answer:

alpha,beta are roots of a quadratic equation ax^2+bx+c=0,then alpha+ beta=-b/a alpha*beta=c/a. Therefore,alpha sq

If alpha,beta are roots of a quadratic equation ax^2+bx+c=0,thenalpha+beta=-b/aalpha*beta=c/aTherefo
