Question

The sum of roots quadratic equations x²-9x+18=0 is

Answer 1

Step-by-step explanation:

We know that equation ax2+bx+c=0

Then sum of roots =a−b and product of roots=ac

Given equation is x2−9x+19=0

Sum of roots =9

Product of the roots =18

Therefore,  the ratio of sum of roots to the product of roots is 9:18 i,e., 1:2.
