Solve the following quadratic equations :
(i) `x^(2)-45x+324=0` (ii) `x^(2)-55x+ 750=0`

Explanation

To solve the given quadratic equations, we will use the method of splitting the middle term. Let's go through each equation step by step.

### (i) Solve the equation: \( x^2 - 45x + 324 = 0 \)

**Step 1: Identify coefficients**
- The equation is in the form \( ax^2 + bx + c = 0 \).
- Here, \( a = 1 \), \( b = -45 \), and \( c = 324 \).
