Best ResponseYou've already chosen the best response.0okay, so u need to know the quadratic formula i believe..do u know it?

Best ResponseYou've already chosen the best response.0but how does that help convert it to general form?

Best ResponseYou've already chosen the best response.0I thought it just helped find the xintercepts..

Best ResponseYou've already chosen the best response.0if i can remember this correctly, i believe u need to first solve to get the values of a,b,c and then you just plug it into the general form... I'm not 100% sure tho... @abb0t, am i remembering this correctly? ;/

Best ResponseYou've already chosen the best response.0I know how to convert it... the problem is the 2 in 2x^2

Best ResponseYou've already chosen the best response.02 in 2x^2 is the problem.... you isolate the x variables getting: y4=2x^2+6x then complete the square and balance the equation: 6/2=3 3^2=9, y4+9=2x^2+6x+9, y+5=2x^2+6x+9 then convert the trinomial into a binomial... thus lies my dilemma

Best ResponseYou've already chosen the best response.0sorry, i'm not very sure, cuz i don't think i remember this correctly ahha and i don't wanna help u wrongly haha @Mertsj probs knows :) good luck!!! :D

Best ResponseYou've already chosen the best response.2\[y=2x^2+6x+4\] \[y=2(x^2+3x+______ )+4\]

Best ResponseYou've already chosen the best response.2Now complete the square by adding (3/2)^2 inside the parentheses: \[y=2(x^2+3x+(\frac{3}{2})^2)+4\frac{9}{2}\]

Best ResponseYou've already chosen the best response.2Now factor: \[y=2(x+\frac{3}{2})^2\frac{1}{2}\]

Best ResponseYou've already chosen the best response.2I want to show you something: \[x^2+6x+9=(x+3)^2\]

Best ResponseYou've already chosen the best response.2Notice the relationship between the coefficient of x and the constant term in a trinomial square.

Mertsj

Best ResponseYou've already chosen the best response.2If you take 1/2 the coefficient and square it, you get the constant term.

Best ResponseYou've already chosen the best response.2So I took 1/2 of 3 and got 3/2. Then I squared it and added it to the x^2 + 3x to get a trinomial square.

Best ResponseYou've already chosen the best response.2Now the (3/2)^2 was inside a parenthesis which has a 2 in front of it so I was really adding 2 times (3/2)^2 which is 2 times 9/4 which is 9/2. So since I could not change the equation, I then had to subtract 9/2.

Best ResponseYou've already chosen the best response.0Okay, yes! I get what you did (: thank you! what were you trying to show me with those other two equations?

Best ResponseYou've already chosen the best response.0oh, that half of the coefficient of x to the second power = the constant. okay, cool
