<h3>
You need to add 4 to both sides</h3>
The x term has a coefficient of 4. Take half of this to get 2, then square it to get 4. This is the value we add to both sides to get x^2+4x+4 = 5. Note how x^2+4x+4 factors into (x+2)^2
---------
Another example: Let's say we started with x^2+6x = 1. To complete the square, we need to add 9 to both sides. I start with 6 (the x coefficient) and cut that in half to get 3, then I squared that to get 9. So we add 9 to both sides getting x^2+6x+9 = 10 which becomes (x+3)^2 = 10
Answer:
14x
Step-by-step explanation:
<em>You have two like terms (numbers with the same letter) so you are going to put those aside for a moment.</em>
<u>Add 5+7+2 </u>and you get 14.
Then, You put the unknown number (x) just beside the 14 to know you are <u>multiply</u>ing <u>x by 14</u> until you find the value.
14x <em>Is your answer</em>

Minimal grade to barely pass would be a C, but you should review and go for at least a B or B+ if you want to pass with a C in the class as a whole.
Answer:
A. Infinitely many
Step-by-step explanation:
9x + 27 = 9(x + 2) + 9
Distribute on the right side.
9x + 27 = 9x + 18 + 9
Combine like terms on the right side.
9x + 27 = 9x + 27
Subtract 27 from both sides.
9x = 9x
Divide both sides by 9.
x = x
x = x is a true statement for every value of x. Therefore, any value you substitute in for x will make the original equation true. That means there is a infinite number of solutions.
Answer: A. Infinitely many
