Question

x^2+23x+k what makes this a perfect square ?

Answer 1

you are trying to find the value of k such that this would be a perfect square?

Answer 2

469/4

Answer 3

- Yes .

Answer 4

sorry 529/4

Answer 5

OK, that would mean you want this equation to be in the form \[(x+b)^2 = x^2 + 23x + k\]

Answer 6

\[x^2 + 2bx + b^2\] so actually 23 is 2*k

Answer 7

so \[k = 23/2, k^2 = (23/2)^2\] as spetzz stated aboved

Answer 8

therefore the equation is \[x^2 + 23x + (23/2)^2\] = \[(x+23/2)^2\]

Answer 9

sorry should be \[b\] in the post above the final equation post

Answer 10

not k
