Find the roots of the following quadratic equation: 2/5x×x-x-3/5=0 |
| Answer» {tex}\\frac { 2 } { 5 } x ^ { 2 } - x - \\frac { 3 } { 5 } = 0{/tex}or,\xa0{tex}\\frac { 2 x ^ { 2 } - 5 x - 3 } { 5 } = 0{/tex}or,2x2 - 5x - 3 = 0or, 2x2- 6x +\xa0x - 3 = 0or, 2x(x - 3) + 1(x - 3) = 0or, (2x + 1)( x - 3 ) = 0{tex}\\therefore \\quad x = - \\frac { 1 } { 2 } , 3{/tex} | |
