Question

9x²+2x+1=0 then x=? what is the x value here

Answer 1

-b+_√b^2-4ac/2a

-2+_√4-36/18
-2+-4√2i/18
[-1+2√2i]\9. [-1-2√2i]\9

so root are complex number because in root it is -32

Answer 2

Since we know that
D=b^2-4ac
In eq
A=9 b=2 c=1
2^2-4x9x1
4-36
-32
Since -32 is less than zero there will be no zero for the polynomial
