Answer the following for the quadratic polynomial q(x)=3x2−x−2q(x)=3x^{2}-x-2. (i) Factorise q(x)q(x) completely. (ii) Using the factorised form, find both zeros of q(x)q(x). (iii) Verify that the sum and product of the obtained zeros satisfy the relations α+β=−ba\alpha+\beta=-\dfrac{b}{a} and αβ=ca\alpha\beta=\dfrac{c}{a} respectively.
