Hope it helps

Answer 2

Answer:

ANSWER

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

2

−5x−12=0

it is in form ax

2

+bx+c=0

a=2

b=−5

c=−12

To find zeroes we will are relation

of coefficients as a formula
