For ax^2+bx+c
when a=1
take 1/2 of b and square it
that is what c should be ideally

p^2-30p=c
-30/2=-15
(-15)^2=225
c=225
(p-15)^2 is factored form


k^2-5k+c
-5/2
(-5/2)^2=25/4
c=25/4
factored form is (x-5/2)^2

If it takes 13 cup of flour to make 14 of a cake, how many cups of flour are needed to make a whole cake?
kvasek [131]

Answer:

Im guessing you meant it takes 1/3 cups of flour to make 1/4 of a cake not "14"

Step-by-step explanation:

in that case you would do

1/3+1/3+1/3+1/3

or 1/3*4

which would be 4/3

or

1 1/3
