Question -The coefficient of x in the equation x2 + px + q = 0 was taken as 17 in place of 13, its roots were found to be -2 and -15, the roots of the original equation are
Options:
A .  3, 10
B .  - 3, - 10
C .  - 5, - 18
D .  18,5
Answer: Option B : B Let the equation (inwritten form) bex2 + 17x + q = 0. Roots are -2, -15. So q = 30, And correct equation isx2 + 13x + 30= 0. Hence roots are -3, -10.
