What is the solution for -42.2=-10.999x+-4.9x^2?

[Shawn Garsed]

Hi everybody,

I was wondering if it's possible to solve this equation:

-42.2=-10.999x+-4.9x^2

Now, I just want to know if it's possible. I'm not asking for the answer.

Greetings,

Shawn

P.S.
A little push in the right direction is always welcome.

Sure it's possible. Hint: Look up how to solve quadratic equations.

4.9x²+10.999x-42.2=0

-42.2=-10.999x+-4.9x^2

add 42.2 to both sides

0 = -4.9x² - 10.999x + 42.2

then use the quadratic equation to solve for x if that's what you're looking for.

-42.2=-10.999x+-4.9x^2

add 42.2 to both sides

0 = -4.9x² - 10.999x + 42.2

Make life simpler for yourself by adding 4.9x² + 10.999x to both sides to get it in the form that Icystrike showed.

then use the quadratic equation to solve for x if that's what you're looking for.

Use the quadratic formula to solve this quadratic equation.
