Answer: 7
5+9-3^2+2
= 14-3^2+2
= 14-9+2
= 5+2
= 7
Since we want it in the form: (x - a)², let's first expand (x - a)² and then equate for the coefficients.
(x - a)² = x² - 2ax + a²
x² + 4x - 15 = x² - 2ax + a²
Now, let's focus on the middle term.
4x = -2ax
4 = -2a
a = -2
Thus, we know that a = -2
Then, we can say (x + 2)² = x² + 4x - 15
x² + 4x + 4 = x² + 4x - 15
Thus, 19 units are needed in order to complete the square to produce:
(x + 2)²
Answer:
The answer is C because they have the same coefficient and variable on both sides (or something like that but its definitely c )
Answer:
look at the domain, where the line is on the x-axis
