Question

find a quadratic polynomial, the sum of whose zeroes is 4 and one zero is 5​

Answer 1

Step-by-step explanation:

Given that,

sum of the zeroes(a+b)=4

one zero=5

Let us assume one of the zero be (a)

so, one zero(a)=5

a+b=4

5+b=4

b=4-5

b=-1

we have a=5,b=-1

product of the Zeroes (ab)=5(-1)=-5

a+b=4

ab=-5

quadratic polynomial=x^2-(a+b)x+ab

=x^2-4x-5

Hence quadratic polynomial is x^2 -4x-5
