  • @patrickJMT for the first step, you divided by 2 because its the coefficient in front of x^2 right?

  • @Alex1996Andria yep!

  • I hate rude people complaining when your just trying to help people out!!!!

  • @naheeda13 welcome to the internet.

  • isn't easier to -3 first... just to get it out the way

  • wait can't 9 over 4 be just 9 ? because the half of 6 is 3 and 3 times 3 is 9 lol PLEASE answer .

  • what will i do with out you ???? ^^

  • hi could you complete the square for 3X^2 + X - 2 = 0. I need to complete the square in order to find the inverse of the quadratic. If you can, can you also help me out with the inverse part as well. Thanks.

  • @neneluvred the door didnt creak lol it was him erasing

  • could you do an equation with a higher coefficient? like 5x2 + 2x + 7

  • @patrickJMT how did you factor to get -3/2 ?

  • May God reward you for this

  • HUH. This is hella hard :(
