You can put this solution on YOUR website! Let's use the quadratic formula to solve for x:
Starting with the general quadratic
the general solution using the quadratic equation is:
So lets solve ( notice , , and )
Plug in a=4, b=-3, and c=3
Negate -3 to get 3
Square -3 to get 9 (note: remember when you square -3, you must square the negative as well. This is because .)
Multiply to get
Combine like terms in the radicand (everything under the square root)
Simplify the square root (note: since we cannot take the square root of a negative value, we must factor to to make the radicand positive. If you need help with simplifying the square root, check out this solver)
Multiply 2 and 4 to get 8
After simplifying, the quadratic has roots of
or
Notice if we graph the quadratic , we get
graph of
