Fill in the blank with a constant, so that the resulting quadratic expression is the square of a binomial.

Fill in the blank with a constant, so that the resulting quadratic expression is the square of a binomial.
x^2 + 48x + ___
This one is easy because the coefficient of the squared term is one.
When you have (x + n)2, multiplied out is x2 + 2nx + n2
In this example, 2nx = 48x therefore n = 24
So n2 = 242, which works out to 576
Put 576 in that blank.
