Best ResponseYou've already chosen the best response.0That one is one you can probably solve like a regular equation: 3x^2=75 x^2=75/3=25 square root both sides and x=5

Best ResponseYou've already chosen the best response.0There are other methods for solving more complicated quadratic equations such as factoring and the quadratic formula.

Best ResponseYou've already chosen the best response.0Quadratic equations come in this format: ax^2+bx+c If you want to use the quadratic formula it's x\[(b \pm \sqrt{b^24ac})/2a\] If you want to factor you can sometimes divide by a GCF. Often you have to put it in this format: (x+k)(x+m). m & k have to be 2 number such that, when you multiply them together you get c, and when you add them together you get b.
