That would first be a conversion factor is a number used to change one set of units to another, by multiplying or dividing. when a conversion is necessasry
The second term would be -3f^3 because when in descending order it is
6f^4 - 3f^3 - 2f^2 + 9f
Simply distribute the -3 across the b and -7.
-3(b - 7) = (-3 * b) + (-3 * -7) = -3b + 21
Hope this was helpful, if it wasn't just drop me a DM explaining what didn't make sense.
Answer:
x=5/2
Step-by-step explanation:
Calculate, rewrite, remove the paretheses
Collect the like terms
Swap sides 75=30x swap to 30x=75
Then divide both sides
Answer:
(-4, 0) and (5/2, 0)
Step-by-step explanation:
if you graph the equation you can see where the curve intersects the x-axis or you can factor the equation into: (2x - 5)(x + 4) = 0
set each factor equal to zero and solve:
2x - 5 = 0
2x = 5
x = 5/2
x + 4 = 0
x = -4
