Question

solve by completing the square
x^2-16x= 10

Answer 1

take the -16 term divide it by 2 and square it then add it to both sides of the equation:
\[\frac{-16}{2}= -8\rightarrow (-8)^2=64\]
so the equation turns into:
\[x^2-16x+64=10+64\]
you can factor the left hand side:
\[(x-8)(x-8)=74 \rightarrow (x-8)^2=74\rightarrow (x-8)^2-74=0\]

Answer 2

\[(x-8)^2=74\]

Answer 3

so x would = 74?

Answer 4

no x=8

Answer 5

y=-74

Answer 6

vertex: ( 8,-74)

Answer 7

are you any good with graphing?

Answer 8

I don't know

Answer 9

i have one i have posted thats been giving me trouble

Answer 10

the answer for this one was in radical form which it did not state, ty for the help you still get a medal

Answer 11

ty

Answer 12

nadeem solve this call vertex from

Answer 13

i see

Answer 14

\[(x-8)^2=10+64\]\[x-8=\pm \sqrt{74}\]\[x=8\pm \sqrt{74}\]

vertex from:
\[x^2-16x-10\]\[1(x-8)^2-10-(1*64)\]\[(x-8)^2-10-64\]\[y=(x-8)^2-74\]
vertex=(8,-74)
