Find the value of k so that the zeros of the quadratic polynomial 3x^2-kx+14are the ratio 7:6 |
|
Answer» let the roots are 7x and 6x. So, sum of roots are 13x , but sum of roots is also -b/a and -b/a = -(-k)/3 So, 13x=k/3 39x=k and product of roots are c/a=42x2 14/3 =42x2 So,x2=1/9 So, x=1/3 So, k=39/3 So, k=13............ Give full solution K=13...... |
