Question

if alpha and beta are the roots of the equation ax2-bx+c=0(a is not equal to 0) then calculate alpha + beta

Answer 1

alpha and beta are the roots of ax² - bx + c = 0

alpha + beta = - ( x- coefficient ) / (x²-coefficient )

= - ( -b ) / a

= b / a

I hope this helps you.

Answer 2

alpha + beta = - b/a
