Question

fond the quadratic polinomial the sum of whose zeroes os 4 and one zero is 5 ​

Answer 1

${\large{\bold{\sf{(x-α)(x-β)}}}}$

${\large{\bold{\sf{(x-4)(x-5)}}}}$

${\large{\bold{\sf{x²-9x+20}}}}$

$\large{\mathbb\blue{MARK}\:\mathbb\green{AS}\:\mathbb\red{BRAINLIEST}}$

Answer 2

let a and b be the zeroes

a+b=4

5+b=4. .........( given: 1 zero is 5)

b=-1

product of zeroes

ab=5*-1

ab=-5

now standard form of quadratic equation is

x^2-Sx+P

put values of S and P ........(S is sum and P is product of zeroes)

x^2-4x-5
