Question

if alpha and beta are the roots of x^2+7x+10=0,find the value of alpha-beta. ASAP​

Answer 1

Step-by-step explanation:

x²+7x+10=0

x²+5x+2x+10=0

x(x+5)+2(x+5)=0

(x+5)(x+2)

alpha=-5

beta=-2

alpha-beta

(-5)-(-2)

-3

Step-by-step explanation:

x²+7x+10=0

x²+5x+2x+10=0

x=-5 ,x=-2

alpha=-5

beta=-2
