Question

find the zeros of the polynomial x2
+2x+1

Answer 1

x²+2x+1= x²+x+x+1
(By splitting the middle term)
=x(x+1)+1(x+1)
=(x+1)(x+1)
=>x+1=0
Hence,x=-1.
Therefore,the zeroes of the polynomial x²+2x+1
are -1,-1.

Hope it helped you.Have a nice day. :)

Answer 2

x²+2x+1
=x²+2x+1=0
x²+1x+1x+1=0
x(x+1)+1(x+1)=0
(x+1) (x+1)
therefore x=-1,x=-1
