Question

A quadratic polynomial whose zeroes are -5 and 1 is
a) x*2 + 4x - 5. b) x*2 + 4x + 5
c) x*2 - 4x + 5. d) x*2 - 4x - 5

Answer 1

Here's your annswer mate
a) X*2+4x-5
:- 2x + 4x - 5
:- X+ 4x - 5÷2
:- X+ 4x - 2.5
:- X+X - 2.5 ÷4
:- 2x - 5
:- X = 5÷2
:- X = 2.5
mark as brainlist pls and check at ur textbook back answer (if)

Answer 2

$\huge\mathbb{SOLUTION:-}$

OPTION (a)

$x^2+4x-5$

This equation has -5 and 1 has

it's zeroes

$\huge\mathbb{EXPLANATION:-}$

1 . For finding the correct

polynomial which has zeroes

as -5 and 1 , we should

substitute the zeroes in the

given equation

2 . After doing all the problem ,

at last i came to know that

option a has -5 and 1 as it's

zeroes
