Find a quadratic polynomial with integral coefficients having both sum and product of roots= 4.5 |
|
Answer» 2x² -9x+9 is the required polynomial. Step-by-step explanation: Given : Sum of root of the QUADRATIC = 4.5 Product of roots of the quadratic = 4.5 General form of a quadratic equation = x² - (sum of the roots)×x + product of roots = x² -4.5x +4.5 Since the quadratic has integral COEFFICIENT we can MULTIPLY the total quadratic by 10 Therefore the quadratic with integral coefficient=10x² -45x+45 Simplifying the equation we GET = 2x² -9x+9 |
