The expanded form for 3.69 is 3+0.6+0.09. How you do that is because the three is a whole number so it stays a whole number, the 6 is in the tenths spot and so it would be 0.6 because that is counting tenths. The 9 is in the hundredths spot so it has to be in expanded form as hundredths. And 2 spots over is hundredths so that is how you get that 9 in expanded form.
450 because you are adding +25

<u>How can </u><u>we</u><u> factor 5x^2 + 26x - 24 = 0 using the completing the square </u><u>method?</u>
Let's solve your equation step-by-step.
First, add 24 to both sides.
Since the coefficient of 5x² is 5, divide both sides by 5.
The coefficient of 26/5x is 26/5. So, let b=26/5.
Then we need to add (b/2)²=169/25 to both sides to complete the square.
Add 169/25 to both sides.
Factor the left side.
Take square root.
Then, add (-13)/5 to both sides.
