Step-by-step explanation:
Answer: 9x^2 - 6x + 8
Step-by-step explanation:
(9x^2 - 2x + 7) - (4x - 1) Subtract like terms
The term 9x^2 doesn't have any other term so it will stay alone.
-2x - 4x = - 6x
7 - (-1) = 8
Put them together to get 9x^2 - 6x + 8
Answer:
Step-by-step explanation:
a
The square root of 20 = 4.47 so a for sure.
But the root of 20 is also -4.48 so that means that 2 and 3 are added to the list
Now what to do about - 8
(- 8)^2 = 64
The square root of 64 = +/- 8
It's kind of slippery but it depends on how you see the problem. It is a bit ambiguous.
I would eliminate - 8 but your instructor may not. Argue that it should not be included, but don't take the argument on forever. Let it go.
a for sure.
b and c I think so.
-8 is iffy.
