<u>ANSWER: </u>
If x =
and x = -3 are the roots of the equation, then values of a and b are 3, -6
<u>SOLUTION:
</u>
Given, quadratic equation is
and its roots are -3 , 
We know that, for any quadratic equation of form
with roots
then,
Sum of roots
= 
Product of roots (
= 
Now, for given quadratic equation
= -3 and
= 
hence Sum of roots = 


on solving we get "a" = 3
Now product of roots = 

b = -6
hence, the values of a and b are 3, -6.
