Question

Write a quadratic polynomial some of whose zeroes is 4 and product is -8

Answer 1

Answer:

(x2 - 4x +(-8)

(x2 -4x -8)

Answer 2

Answer:

The required quadratic polynomial is $x^{2} -4x-8$

Step-by-step explanation:

General form of a quadratic polynomial is

$ax^{2} +bx+c$

where a, b, c are real numbers

Sum of roots= $\frac{-b}{a}$

Product of roots = $\frac{c}{a}$

That is,

$x^{2} -(sum of roots)x +(product of roots)$

So, the required quadratic polynomial is

$x^{2} -4x-8$

The correct answer is $x^{2} -4x-8$
