Question

find a quadratic polynomial whose zeros are 3 and minus 5

Answer 1

Answer:

Step-by-step explanation:

Sum of zeroes = 3-5=-2

Product of zeroes = 3 x -5 = -15

Quadratic polynomial = k{x^2 -( sum of zeroes)x + product of zeroes}

Now, put the values

= K{x^2+4x-15 }

Hence, the polynomial is

x^2+4x-15
