Question

if 2 and I/2 are two zero
of polynomial ax^2 + 5x + b
show that a = b​

Answer 1

ANSWER :–

GIVEN :–

A POLYNOMIAL ax² + 5x + b = 0

TO PROVE :–

a = b

SOLUTION :–

● WE KNOW THAT PRODUCT OF ROOTS = c/a

HERE –

a = a , b = 5 and c = b

=》 PRODUCT OF ROOTS = c/a = (2)(½)

=》 b/a = (2)(½)

=》 b/a = 1

=》 b = c (Hence proved)
