If the zeros of the polynial f(x);x3 -3x2+x+1are a-b;a;a+bfind aand b |
| Answer» Let alpha beta and gamma are the three zeros of the given polynomial FX and Alpha is equals to a minus b beta is equals to a and gamma is equals to A + B by sum of zeros we have alpha + beta + Gamma is equals to minus minus 3 by 1 so we get 3 a is equals to 3 then a is equals to 1 by this we get alpha × beta × Gama is equals to -1 and putting the value of a in this equation we get -b^2 =-1 thus a is equals to 1 and b is equals to 1 | |
