Question

1. If the sum and product of zeroes of the quadratic polynomials are v5
and-2 respectively then find the quadratic polynomials.​

Answer 1

Answer:

If α and β are the roots of the quadratic polynomial

then eq

n

becomes

x

2

−(α+β)x+αβ

Here sum =5 and product =−2

∴ quadratic polynomial = x

2

−5x−2

Answer 2

Answer:

k[x^2  -5x - 2]

Step-by-step explanation:

•  given ,
•       sum of zeroes = 5

       product of zeroes=  -2

  hence,

               we know that   quadratic  polynomial

= k [ x^2 - (sumof zeores)x + (product of zeroes)]     where  k = constant

=  k [x^2 - (5)x + (-2)]

=k[x^2-5x-2]
