WORK SHEET
1. Find zeroes of the polynomial 6x + 5x2 + 7x - 20 and verify the relation between zeroes and
coefficients.​

Answer 1

Answer :

6ײ -.3 - 7x -3=0

= 6x² + 2x -9x - 3 = 0

= 2x ( 3x + 1) -3 (3x + 1 ) = 0

= (2x -3 ) (3x +1 ) = 0

zeros = 3/2 , -1 / 3

a+B = -b/a =3/2 - 1/2 = 7/6 = (-7) /6 = -b/a

a/B = c/a = (3/2) (-1/3) = -1/2 = -3/6 = c/a

Hence proved
