Well, you are subtracting g(x) from f(x) so:
√x-x-(2x^3-√x-x) which is:
√x-x-2x^3+√x+x (you have your signs wrong at the bottom of your post)
Now you would simply combine like terms (do your addition and subtraction of like terms)
-2x^3+2√x
So the answer is D.
An easy way to do it is to guess and try all the combinations
or the math way is to find all the factors
76=2*2*19
so the answer is 2 times the square root of 19 or 8.72
Answer:−2x^3+8x^2−4x
Step-by-step explanation:
Equation:-2x(x2-4x+2)
=(−2x)(x^2+−4x+2)
=(−2x)(x^2)+(−2x)(−4x)+(−2x)(2)
=-2x^3+8x^2-4x
The first one pretty sure :))))
