Answer:
2
Step-by-step explanation:
15+-13 = 2
A. –x3 + 6x2 + 9
B. –x3 + 2x2 – 9
C. 5x3 – 2x2 – 2x – 9
D. 5x3 – 2x2 + 2x + 9
The difference between the polynomials (5x³-4x²)-(6x²-2x-9) is 5x³-2x²+2x+9 and the right option is D. 5x³-2x²+2x+9.
A polynomial is an expression of more than two algebraic terms
To calculate the difference between both polynomials we apply the techniques below.
Given:
Substrat each like term accordingly.
Hence, the difference between the polynomials (5x³-4x²)-(6x²-2x-9) is 5x³-2x²+2x+9 and the right option is D. 5x³-2x²+2x+9.

A.5
B.–5
C.0
D.–1
-5+ =-5
Replace the blank place by x
-5+x=-5
Simplify both sides of the equation
x-5=-5
Add 5 to both side sides
x-5+5=-5+5
x= 0
Answer : C
