Question

find out a quadratic polynomial whose zeroes are 4and5is..​

Answer 1

Answer:

if you want to form a polynomial whose roots are given then,

Step-by-step explanation:

given that roots are 4 and 5

let x=4 ==   ==  >   x-4=0

x=5 ==  ==  >  x-5=0

multiply the both above we get,

(x-4)*(x-5) =x^2-5x-4x+20=0

simplifying we get ,

$x^{2}$-9x+20 = 0

which is the required polynomial
