Question 88211
<pre><font size = 5 color = "darkpurple"><B>
I need help solving by using the quadratic formula 

              3x² - x = 3 

Get 0 on the right by adding -3 to both sides:

          3x² - x - 3 = 0

Use the quadratic formula, which gives 
the solution to

          ax² + bx + c = 0

The quadratic formula is
                  ______ 
            -b ± <font face = "symbol">Ö</font>b²-4ac
        x = —————————————
                2a 

Compare 

           3x² - x - 3 = 0
to
           ax² + bx + c = 0

and we see that:  a = 3; b = -1; c = -3

                      ______________
             -(-1) ± <font face = "symbol">Ö</font>(-1)²-4(3)(-3)
        x = ————————————————————————
