if one root of the quadratic equation is 3+2root5/4.then find the other root\xa0 |
| Answer» According to the question,\xa0One of the\xa0roots of the quadratic equation =\xa0{tex}\\frac { 3 + 2 \\sqrt { 5 } } { 4 }{/tex}{tex}\\because{/tex}\xa0Coefficient are rational{tex}\\therefore{/tex}\xa0other root of the equation\xa0will be\xa0{tex}\\frac { 3 - 2 \\sqrt { 5 } } { 4 }{/tex}\xa0(If coefficient are rational, then the roots are always conjugate rational) | |
