1. -9 need to multiple to both number
-9 X n= -9n -9 X -3 = 21
-9n + 21
2. -10 X 9n = -90n -10 X 3 = -30
-90n - 30 - 8
-90n - 38
Hope that helps
10=N I’m not 100% sure hope this helped :)
Answer:
the quickest way would be to "complete the square"
on x^2 + 5x - 7
you will end up with (x+2.5)² = 13.25
or
y = (x+2.5)²-13.25
the vertex
VERTEX: (-2.5,-13.25)
Solution/X-Intercepts: -6.14 AND 1.14
