Question 3 A quadratic polynomial, the product and sum of whose zeroes are 5 and 8 respectively is (a) π[π₯^2β8π₯+5] (b) π[π₯^2+8π₯+5] (c) π[π₯^2β5π₯+8] (d) π[π₯^2+5π₯+8]
The quadratic polynomial is
x2 β (Sum of roots)x + Product of roots
Putting values
π₯^2β5π₯+8
We can multiply any constant to this polynomial
So, required quadratic polynomial is
π(π^πβππ+π" " )
So, the correct answer is (c)
