Best ResponseYou've already chosen the best response.0I just need to know what to plug in. like what does k and h equal??

Best ResponseYou've already chosen the best response.1Let's start with the first one: y = x2 + 14x + 29 The key to doing this, is by completing the square for x: y = x2 + 14x + 29 Now add 49 and substract 49, because 49 = (14/2)^2 y = x2 + 14x + 49  49 + 29 but, x2 + 14x + 49 = (x+7)^2 so y = (x+7)^2  30 so h=7, k = 30

Best ResponseYou've already chosen the best response.1Sorry, I made a mistake haha. y = (x+7)^2  20 so h = 7 and k = 20

Best ResponseYou've already chosen the best response.0so is the whole equations supposed to have exact numbers? where do i plug in x^2 14 x and 29?

Best ResponseYou've already chosen the best response.1read what I did. It explains everything. You just transform the equation.

Best ResponseYou've already chosen the best response.0im so confused i meant i needed the form with the correct numbers but are you solving for the actual value?

Best ResponseYou've already chosen the best response.1I'm not solving anything.... I have the correct form. y = (x+7)^2  20

Best ResponseYou've already chosen the best response.1yes, but I'm just showing how the general form relates to what I got. Nevermind. Just look at the answer: y = (x+7)^2  20

Best ResponseYou've already chosen the best response.0could you show me how do the second one? i am still so confused. Sorry, thank you.

Best ResponseYou've already chosen the best response.1y = 3x2  24x + 10 First factor out the 3: y = 3(x2  8x + 10/3) add and subtract: (8/2)^2 = 16 y= 3(x2  8x + 16  16 + 10/3) Try to go further from here
