Question

find quardaratic polynomial the sum of whose zeroes is 4 and one zero is 5
​

Answer 1

Step-by-step explanation:

Let the roots be x and y

Given one of them is 5

sum of roots is 4

x + 5 = 4

x = 4 - 5

x = -1

product of the roots is -5

so the equation is

x² - (4)x + (-5) = 0

x² - 4x - 5 = 0
