If one zero of the polynomial x2\xa0+ a is (-3) then find its other zero. |
| Answer» If -3 is a zero of x2 + a, then(-3)2 + a = 0=> 9 + a = 0=> a = -9Then the given polynomial will be x2\xa0 - 9.=> (x + 3)(x - 3)=> x + 3 = 0 and x - 3 = 0=> x = -3 and x = 3Therefore the other zero of given polynomial is 3. | |
