<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.
