Solve for u. 4u²+3=-8u
If there is more than one solution, separate them with commas.
If there is no solution, click on "No solution."

u =   ;  u =

Step-by-step explanation:

4u² + 3 = -8u

4u² + 3 + 8u = -8u + 8u       (add 8u both sides)

4u² + 8u + 3 = 0                    simplify

using quadratic equation:

      - 8 ± √ (8² - 4 * 4 *3)

u = ------------------------------

               2 * 4

u =   ;  u =

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

yes   because as the functions are graphed they eventually will intersect unless otherwise
