Question

find the zeroes of the polynomial x²- 2x- 3​

Answer 1

Answer:

mine is coming x2=-1 i dont know if it is right

Answer 2

Answer:

f(x)=x²-2x-3

Now substitute f(x)=0

x²-2x-3=0

x²-3x+x-3=0

x(x-3)+1(x-3)=0

now we have

(x+1)&(x-3)=0

x+1=0

x= -1

now,

x-3=0

x=3

Therefore zero of polynomial is -1&3.
