Answer:
cos²A - cosA - 6
Step-by-step explanation:
Given
(cosA + 2)(cosA - 3)
Each term in the second factor is multiplied by each term in the first factor, that is
cosA(cosA - 3) + 2(cosA - 3) ← distribute both parenthesis
= cos²A - 3cosA + 2cosA - 6 ← collect like terms
= cos²A - cosA - 6
1. vertical line
2. standard form
3. slope-intercept form
4.horizotal line
5.slope=7 y-intercept= 2
6. slope= 2 y-intercept= -6
7. slope=1 y-intercept=0
Should I answer all the questions? or a specific one?
The curved line crosses the X-axis at -6 and 5
The answer is the second choice.
