Question 3 A quadratic polynomial, the product and sum of whose zeroes are 5 and 8 respectively is (a) š[š„^2ā8š„+5] (b) š[š„^2+8š„+5] (c) š[š„^2ā5š„+8] (d) š[š„^2+5š„+8]
The quadratic polynomial is
x2 ā (Sum of roots)x + Product of roots
Putting values
š„^2ā5š„+8
We can multiply any constant to this polynomial
So, required quadratic polynomial is
š(š^šāšš+š" " )
So, the correct answer is (c)
