Question 924902: Use the quadratic formula to solve the following quadratic equations, giving your answer to 2 decimal places in each case.
X2+6x+4=0
3x2- 6x+2=0
6x2-9x-4=0
The 2 after the x is squared
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! xx + 6x + 4 = 0
3xx - 6x + 2 = 0
6xx - 9x - 4 = 0
