justineeBest ResponseYou've already chosen the best response.0
then 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

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

You subtracted 100 though ^

DecartBest ResponseYou've already chosen the best response.1
you add 48 to the other side and then also the 100 and the quadratic = 148

DecartBest ResponseYou've already chosen the best response.1
then you can factor the left side

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

DecartBest ResponseYou've already chosen the best response.1
you did it rite just set the equation = 0 then subtract 49 from both sides so 2x^220x=48

DecartBest ResponseYou've already chosen the best response.1
then complete the square and add the 100 to both sides
 5 months ago

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

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

Ok I got it thanks! and one more question
 5 months ago

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

DecartBest ResponseYou've already chosen the best response.1
c is a constant most likely just move it to the other side and complete the square

justineeBest ResponseYou've already chosen the best response.0
what is that going to give me?
 5 months ago

justineeBest ResponseYou've already chosen the best response.0
and what would be the next step
 5 months ago

justineeBest ResponseYou've already chosen the best response.0
0 = (x2  38x ___) +c ?
 5 months ago

DecartBest ResponseYou've already chosen the best response.1
square the 38 and do the same to both sides
 5 months ago

DecartBest ResponseYou've already chosen the best response.1
so that is on both sides
 5 months ago

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

DecartBest ResponseYou've already chosen the best response.1
right now you should be able to factor the quadratic which is the point of completing the square
 5 months ago

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

DecartBest ResponseYou've already chosen the best response.1
right it will be the same number it is squared
 5 months ago

DecartBest ResponseYou've already chosen the best response.1
and the first equation was x^210+25=49
 5 months ago

DecartBest ResponseYou've already chosen the best response.1
with the second you can't do anything it is most likely to show how you did the work
 5 months ago

justineeBest ResponseYou've already chosen the best response.0
how would i write tht in intercept form
 5 months ago

justineeBest ResponseYou've already chosen the best response.0
no I also have to rewrite tht in intercept
 5 months ago

DecartBest ResponseYou've already chosen the best response.1
the x intercept is +or(7/5,0)
