Question from Tharshini, a student: Given a and B are the roots of the quadratic equation x^2+4x+7=0. Form the quadratic equation which has the roots |
Hi Tharshini,
Use the general quadratic to find the roots $a$ and $B.$ Form the quadratic that has roots $3a-1$ and $3B-1$ and simplify. Use the general quadratic to solve find the roots of this equation and verify they are $3a-1$ and $3B-1.$
