If x=2/3 and x=-3 are the roots of the equation ax^2+7x+b=0 find the values of a and b

ANSWER:  

If x = and x = -3 are the roots of the equation, then values of a and b are 3, -6

SOLUTION:

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.
