Find all real and complex solutionsa)x²+2x+1=0b)x²+4=0c)9x²-4 x-14=0d)8x²+4x+32=0

Step-by-step explanation:

a). x²+2x+1=0

   x = -1 , - 1

Therefore the roots are real.

b). x²+4=0

     x²= -4

     x = 2 , -2

Therefore the roots are real.

c) 9x²-4x-14 =0

  x =  

   =

   =

   =

 x =

    = -1.48

x =

  = 1.04

Therefore, x =  1.04 ,  -1.48

Hence the roots are real

d) 8x²+4x+32=0

x =  

   =

   =

   =

 x =

    = -2.2

x =

  = 1.73

Therefore, x =  1.73 ,  -2.2

Hence the roots are real

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
