Detailed Solution

p(x)= x 2 (   Sum of zeroes )x+   Product of zeroes
Given that, one of the zeroes =6   and sum of zeroes =0  .
Sum of zeroes = First zero + Second zero = 0.
Substitute First zero = 6  6 + Second zero = 0
Second zero = – 6
We know that, the required polynomial is, p(x)= x 2  (Sum of zeroes) x + Product of zeroes.
Let us substitute the values,
p(x)= x 2 0x+(6x6)   p(x)= x 2 +(36)   p(x)= x 2 36  
Therefore, the representation of Highway Underpass whose one zero is 6 and sum of the zeroes is 0 is x 2 36  .
The correct option is (2).
