Question

form a quadratic polynomials 4 and -2 as the sum and product of its zeroes respectively

Answer 1

Answer:

x^2-4x-2

Step-by-step explanation:

Sum of zeroes = 4

Product of zeroes = -2

So, by formula of quadratic polynomial,

x^2-(Sum of zeroes)x+(Product of zeroes)

x^2-4x-2

Answer 2

Step-by-step explanation:

Sum of the zeroes = 4

Product of the zeroes=-2

let ax^2+bx+c be its req. poly. and let alpha and beta be its zeroes

we have,

sum of the zeroes =-(4)=-b/a

Product of the zeroes=-2=c/a

if a=1

then b=-4

and c=-2

therefore, one quardratic equation which fits the given conditions is

x^2-4x-2

any other quad. equation which fits the given conditions is in the form of

k (x^2-4x-2)

where k is a non -zero real no....
