Solve for the roots in simplest form by completing the square <br> 6x^2+120x+2070=0
Kitty [74]

Answer:

Step-by-step explanation:

First, we can divide out the common factor, 6

6x^2 + 120x + 2070 = 0\\x^2 + 20x + 345 = 0\\

Now we complete the square

(x^2 + 20x + (\frac{20}{2})^2) + 345 - (\frac{20}{2})^2\\(x^2 + 20x + 100) + 345 - 100\\(x+10)^2 + 245\\

(x+10)^2 = -245\\x + 10 = \sqrt{-245}\\x = i\sqrt{245}  - 10\\x = -10 \pm i\sqrt{245}
