Best ResponseYou've already chosen the best response.0then i rewrote that into: y = 2(x^2  20x ____) 48 20/2 = 10 then square it and I got 100 y = 2(x^2  20x +100) 48

Best ResponseYou've already chosen the best response.0then I added 100 to both sides and I got: y + 100= 2(x  10)^2 48 100 100  y = 2(x  10)^2  148

Best ResponseYou've already chosen the best response.0You subtracted 100 though ^

Best ResponseYou've already chosen the best response.0you add 48 to the other side and then also the 100 and the quadratic = 148

Best ResponseYou've already chosen the best response.0then you can factor the left side

Best ResponseYou've already chosen the best response.0can you show me that in steps? like from the beginning

Best ResponseYou've already chosen the best response.0you did it rite just set the equation = 0 then subtract 49 from both sides so 2x^220x=48

Best ResponseYou've already chosen the best response.0then complete the square and add the 100 to both sides

Best ResponseYou've already chosen the best response.0so it'd be 0 = 2(x^2  20x + 100) 48 ?

Best ResponseYou've already chosen the best response.0why do I need to factor that

Best ResponseYou've already chosen the best response.0Ok I got it thanks! and one more question

Best ResponseYou've already chosen the best response.0How would I solve: x^2  38x + c also by completing the square

anonymous

Best ResponseYou've already chosen the best response.0c is a constant most likely just move it to the other side and complete the square

Best ResponseYou've already chosen the best response.0what is that going to give me?

Best ResponseYou've already chosen the best response.0and what would be the next step

Best ResponseYou've already chosen the best response.00 = (x2  38x ___) +c ?

Best ResponseYou've already chosen the best response.0square the 38 and do the same to both sides

anonymous

Best ResponseYou've already chosen the best response.0so that is on both sides

anonymous

Best ResponseYou've already chosen the best response.0okay so far i have: (x^2  38x + 361) = 361 c

Best ResponseYou've already chosen the best response.0right now you should be able to factor the quadratic which is the point of completing the square

anonymous

Best ResponseYou've already chosen the best response.0so like: ____ x___ = 361 ____+___= 38

anonymous

Best ResponseYou've already chosen the best response.0right it will be the same number it is squared

Best ResponseYou've already chosen the best response.0and the first equation was x^210+25=49

Best ResponseYou've already chosen the best response.0with the second you can't do anything it is most likely to show how you did the work

Best ResponseYou've already chosen the best response.0how would i write tht in intercept form

anonymous

Best ResponseYou've already chosen the best response.0no I also have to rewrite tht in intercept

Best ResponseYou've already chosen the best response.0the x intercept is +or(7/5,0)
