Find the roots of the quadratic equation `6x^2-x-2=0`. |
|
Answer» equation is `6x^2 - x-2=0 ` let `alpha & beta` be two terms such that `alpha+ beta= -x` `alpha* beta= (6x^2)(-2) = -12x^2` `alpha= -4x & beta= 3x` `6x^2 - 4x+3x-2=0` `2x[3x-2]+1[3x-2]=0` `(2x+1)(3x-2)=0` `2x+1=0` `x=-1/2` answer and `3x-2=0` `x=2/3` answer |
