Question

write the sum and product of the zeroes of polynomial x3 -4x

Answer 1

Sum = alpha + beta. -b/a = -(-4)/1 = 4
Product = alpha × beta. c/a = 0/1 = 0

Answer 2

Answer:

Let p ( x ) = x³ - 4x .

Compare p( x ) with standard form ax³ + bx² + cx + d [cubic polynomial]

a = 1 , b = 0 , c = -4 , d = 0

1 ) sum of the zeroes

= - b/a

= - 0/1

=   0

2 ) product of the zeroes

=  d/a

=  0 / 1

=  0
