Question

if alpha and beta are the roots of the equation x^2-7x+12=0 then alpha minus beta is

Answer 1

Answer:

Step-by-step explanation:

x^2+7x+12=0 is a given quadratic equation.

Alpha and beta are the roots of the given equation.

So, a=+1,b=+7,c=+12(from the given equation).

Sum of the roots=Alpha +beta=-b ÷a

=(-7)÷(+1)

=-7

Product of the roots=Alpha*beta=c ÷a

=(+12)÷(+1)

=+12
