Question

what is equivalent to the following equation y=x^2+4x+11

Answer 1

the compressed form of it i would assume

Answer 2

add 4 and subtract 4 to compress it

Answer 3

add 4 where and subtract where?

Answer 4

y=x^2+4x+(4-4)+11

y=(x^2+4x+4)-4+11

y=(x+2)^2 +7

Answer 5

in other words, the method is generally refered to as "completeing the square" if you wanna read up on it

Answer 6

So y=(x+3)^2+53 would be the same way?

Answer 7

if they want a different form, then that one would need to be expanded

Answer 8

(x+2) * (x+3) = x^2 +6x + 9

y = x^2 +6x + 9 + 53

Answer 9

Thanks
