Question

find the zeros of the quadratic polynomial 2x^2-5x and verify the relationship between the zeros and coeffcients​

Answer 1

Answer:

Step-by-step explanation:

First find the factors of 1. They are 1 and -1.

Then apply each on the place of x.

Let x=1

p(1)=2*1^2-5*1+1

(apply like this)

There's no zero of the given polynomial.

Hope it helps...

Answer 2

Step-by-step explanation:

find the zeros of polynomial

p(x)=2x

2

−5x−12 and verify

the relationship between its zeros and coefficients

We will use side charge method

2π

−5x−12=0

it is in form ax

+bx+c=0

a=2

b=−5

c=−12

To find zeroes we will are relation

of coefficients as a formula
