9b - 12b² factorised would be 3b(3 - 4b).
You can find this as you must first find a common factor between 9b and -12b², which would be 3b. We can then take this out of the bracket and divide both terms by 3b to get the final answer, which leaves us with 3b(3 - 4b).
I hope this helps!
Answer:
Step-by-step explanation:
Given:
- Focus = (-5,-4)
- Directrix = -6
To find:
Locus of Parabola (Upward/Downward)
Where:
- (a,b) = focus
- c = directrix
Hence:
Cancel square root by squaring both sides as we get:
Solve for y-term:
f(x) = -3x - 5, g(x) = 4x - 2
(f - g)(x) = f(x) - g(x) = (-3x - 5) - (4x - 2) = -3x - 5 - 4x + 2 = (-3x - 4x) + (-5 + 2)
(f - g)(x) = -7x - 3
Answer: y=x+3/x-8
Step-by-step explanation:
Rewrite the divisions as fractions and you fine this answer.
