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
