If 2/3 and -3 are the two roots of the quadratic equation ax² + 7x + b = 0, then let me calculate the values of a and b.

Given equation is

It is given that -3 and are the roots of the equation.

Therefore, they must satisfy the equation.

⇒

………eq (1)

And

⇒

⇒………eq(2)

Now, putting the value of b in eq(2)

Therefore putting the value of a in eq(1).

Therefore, putting the value of a and b in the equation

Hence , the required equation is
