-3/8 -1/10 = (-15 -4)/40 = -19/40
so this mean that choice D. is right sure
hope this will help you
Answer:
Point D
Step-by-step explanation:
Any arithmetic operation on polynomials except division* will result in a polynomial. Appropriate choices are ...
A. (x^2+2) (x-1)
C. (x+1) plus (X^2-3X -2)
D. (X +5)-(3X +6)
E. (4/8)x . . . . . but not if you mean 4/(8x)
_____
* For division, the result <em>may</em> be a polynomial. In the specific example given here for B, it is not.
