The answer is 12, 13 and 16
Answer:
x² + 2ax + a² + 5x + 5a + 4
Step-by-step explanation:
Formula -
( a + b )² = a² + 2ab + b²
Steps -
( x + a )² + 5 ( x + a ) + 4
x² +2ax + a² + 5 ( x + a ) + 4
x² + 2ax + a² + 5x + 5a + 4
X=-15 because you have to add 3 on both sides
<span>Part C: Plug in any values for x, get the y values, re-write them as (x,y) coordinates and graph.
Sorry, I do not know the other answers, but Part C was easy</span>
