The sum and product of the zeroes of a quadratic polynomial are 3 and -10 respectively. The quadratic polynomial is (a) x2 – 3x + 10 (b) x2 + 3x – 10 (c) x2 – 3x – 10 (d) x2 + 3x + 10

Answer»

(c) x2 – 3x – 10 

Given: 

Sum of zeroes, α + β = 3 

Also, product of zeroes, αβ = –10 

∴ Required polynomial = x2 – (α + β) + αβ = x2 – 3x – 10
