For the equation kx^2-(1+k)x+(3k+2)=0, the sum of the roots is twice their product. find k and the 2 roots
Answers: 3
the sum of its roots is 
and the product of its root is 
![\frac{k+1}{k}=2[\frac{3k+2}{k}]](/tpl/images/0462/9458/a393b.png)
⇒Multiply both sides by k
![\frac{-3}{5}x^{2}-[1+\frac{-3}{5}]x+[(3)(\frac{-3}{5})+2]=0](/tpl/images/0462/9458/f0f62.png)
⇒ Multiply equation by 5
⇒ Multiply equation by -1
⇒ use factorization to find rootsAnother question on Mathematics
