Completing the square is done as follows:
1. Write the equation in a way that the constants are in the right side while the terms with x are on the left.
<span>9x2 +54x = 7
</span>
2. Make sure that the coefficient of the x^2 term is 1.
<span>9(x2 + 6x) = 7
</span>
3. Adding a term to both sides that will complete the square in the left side. This is done by dividing the coefficient of the x term by 2 and squaring it. Note: The same amount should be added to the right side to balance the equation.
<span>9(x2 + 6x + 9) = 7 + 81
9(x+3)^2 = 88
</span>
The LCM of 15 and 25 is 75
The LCM is the smallest number that you can get from multiplying both numbers.
multiples of 15: 15, 30, 45, 60, 75...
multiples of 25: 25, 50, 75....
as you can see, 75 is the first number to pop up in both.
