Question

y^2-8y+16=25

Answer 1

9,-1?

Answer 2

y^2 - 8y + 16 = 25

move the 25 to the other side so it = 0

Answer 3

i can work it out so far lol but im catching on

Answer 4

\[(x=4)^2=25\]
\[x-4=5\]
\[x=9\]
\[x-4=-5\]
\[x=-1\] yup

Answer 5

y^2 - 8y + 16 - 25 = 0

y^2 - 8y - 9 = 0

a = 1
b = -8
c = -9

use the formula i stated before to work it out :)

and the answer you have given is correct

Answer 6

or if you prefer
\[x^2-8x-9=0\]
\[(x+1)(x-9)=0\]
\[x=-1,9\]

Answer 7

lol i did and it worked out. thanks yall!
