What number must be added to the expression below to complete the square x^+5x

Step-by-step explanation:

The given expression is

Since the coefficient of the quadratic term is 1, you must add the square of

which is

We square both the numerator and the denominator to obtain,

This will give us

Step-by-step explanation:

We are given the following expression and we are to complete its square:

To complete the square of the above expression, we will divide the coefficient of x by 2 and add its square to the expression.

Since the coefficient of x here is 5, so we will divide it by 2 and add its square to get:

Therefore, the missing term to complete the square of the given expression is .

47 - 90 = 43

43 - 180 = x

x = 137
