Question

A quadratic polynomial whose zeroes are 5 and -3, is

Answer 1

Answer:

Required quadratic equation is x²-2x-15=0

Step-by-step explanation:

Given zeroes are 5 and -3

α=5 and β=-3

Sum of zeroes=5-3=2

Product of zeroes=(5)(-3)=-15

Quadratic polynomial can be given as

x²-(α+β)x+αβ=0

x²-2x-15=0

Required quadratic equation is x²-2x-15=0
