4p^2 + 4p - 5
As the expression cannot be factored in it's current form, we need to check if splitting the middle term is possible.
<em><u>List factors of -20.</u></em>
-5 * 4
5 * -4
-10 * 2
10 * -2
-20 * 1
20 * -1
<u>None of the factors added together result in positive 4.</u>
Because splitting the middle term is not possible, and we cannot simplify this expression any further:
This expression cannot be fully factored.
Always place it out of 9. For example, 0.333= 3/9, or if simplified, 1/3.
0.5555? this will be 5/9.
for the other way around, make it a repeating decimal, such as 4/9, make that 0.444
If it is 33/99, or even 333/999, the rule should be the same.
To do 130% increase you multiply by 1.3 so you do 810 × 1.3 = 1053
