Question

If S denotes sum of roots and P denotes product of roots, then for the quadratic equation 2x² - 5x-1= 0, which of the following will be equal to S/P ?

Answer 1

Step-by-step explanation:

sum of roots= alpha + beta = -b/a = -(-5)/2=5/2=S

product of roots= alpha×beta=c/a= -1/2=P

S/P=5/2×2/-1= -5
