Best ResponseYou've already chosen the best response.0Also sometimes you would have to manipulate your equation to get it in that form but in this case it's set up nicely for you

Best ResponseYou've already chosen the best response.0So the x2 can be written as 2x because they are communitive terms. Since the 2x and 5x are like terms, they can combine so 2x5x = 3x. Ok. Now, since u want to use quadratic u need to assign an a b and c value. The a value is the coefficient of an x^2 in a quadratic equation. Since u don't have a quadratic equation, the coefficient is 0. So the a value is zero. The b value is the 3 and the c value is the number without an x (I don't remember what it was.) Plug the a, b and c values into the quadratic equation and solve. I hope that helps, because i am not good at explaining things. If u still don't understand, I'm sure Kahn academy has a video on it

Best ResponseYou've already chosen the best response.2thats what i have above xD \[\frac{ 5+\sqrt{1} }{ 2}\] \[\frac{ 5\sqrt{1} }{ 2}\] I did this because we have a plus and minus sign so we need 2 seperate equations
