_____________________________
3 less: -3
difference of 16p and 15p: 16p - 15p = p
is equal to: =
the difference of 3 and 1/2: 3 - 1/2 = 2.5
p - 3 = 2.5
Isolate the p. Note the equal sign. What you do to one side, you do to the other. Add 3 to both sides
p - 3 (+3) = 2.5 (+3)
p = 2.5 + 3
p = 5.5
5.5 is your answer for p
hope this helps
Answer:
(5x + 3)² + 3
Step-by-step explanation:
25x² + 30x + 12 =
= (25x² + 30x) + 12
How do we make 25x² + 30x into a perfect square?
25x² is the square of 5x, so our binomial that is squared will start with
(5x + ___)²
We need to find the number that is added to 5x inside the parentheses.
The middle term of the squared binomial is 2 times the first term times the second term.
2(5x)b = 30x
b = 3
The binomial is (5x + 3).
When we square it, the last term will be 9. We need to add 9 to 25x² + 30x to have a perfect square. Then we also need to subtract 9 to not change the value of the expression.
= (25x² + 30x + 9) + 12 - 9
= (5x + 3)² + 3
