If are the roots of the equation , find the values of a and b. (CBSE 2016)

Given: If are the roots of the equation
To find:  the values of a and b.
Solution: 
Quadratic equation in roots form:

(x – a)(x – b) = 0, where a and b are the roots

Given, are the roots of the equation

Quadratic equation is,

(x – 2/3)(x + 3) = 0

⇒ x² -2x/3 + 3x – 2 = 0

⇒ 3x² +7x – 6 = 0

On comparing with

We get, a = 3 and b = -6
