The full quadratic expression is expressed as follows:
x² - 5x + 6.25
An equation is the equality that has mathematical expressions on both sides of it, they can be functions, polynomials or others, there are no limits for them.
Equations can be graphed, just like a function.
To solve this problem we must complete square in the expression, it is necessary to note that perfect square trinomial has the form of:
(a - b)² = a² - 2ab + b²
x² - 5x + ?
5x = 2xb
2b =5
b = 5/2
Let's complete the square
x² - 5x + (5/2)²
x² - 5x + 25/4
x² - 5x + 6.25
