Complete the square x^2 + 12x + 9 - 10x + 1
Enter your answer in the form a(x + u)^2 + v, where a, u, and v are replaced by numbers.
We can simplify the equation to \(x^2 + 2x + 10\).
Because the leading coefficient is 1, we know \(a = 1\)
Now, notice that \(u\) must be half of the coefficient of x, meaning \(u = 1\).
Now, expand what we have, and identify what we need to add.
Can you take it from here?
