Solve for the roots in simplest form using the quadratic formula:<br> 4x2 + 4x = -5
weqwewe [10]

Answer:

Step-by-step explanation:

Move all terms to one side

4x^2 + 4x + 5 = 0

Plug into quadratic formula

x = (-4 <u>+</u> \sqrt{16 - 4(4)(5)}) / 2(4)

  = (-4 <u>+</u> \sqrt{-64})/8

At this point, there are no real answers. The roots to this equation are complex.

x = (-4 <u>+</u> 8i)/8

  = (-1 <u>+</u> 2i)/2
