Answer» ANSWER:- 7x^2 - 12x + 18 = 0 ------------------(1) the SUM of two roots are =( -coefficient of x/ coefficient of x^2) ={-(-12) /7} =(12/7) the PRODUCT of two roots are =( coefficient of x^0 / coefficient of x^2) =(18/7) The ratio of the sum and product of the roots of the equation 7x^2 - 12x + 18 = 0 is (12/7):(18/7)=2:3 The required ans is 2:3. |
