Question

Find the zeroes of the polynomial x²-2x-80 and verify the relationship between zeroes and the co efficient​

Answer 1

Answer:

x

Step-by-step explanation:

x²-10x+8x-80

x(x-10)+8(x-10)

(x+8) (x-10)

x=-8 x=10

sum of zeroes= -b/a

-8+10= -(-2)/1

2=2

product of zeroes=c/a

-8×10=-80/1

-80=-80
