2. 3x²+6-2x+5x-4x²+9

A.-X²+3X+15
B.7X²+3X+3
C.X²-3X+15
D.-X²+7X+15

3. 2X²+6X-7X+8=3X²+1
A.2x²+x+9
B. -2x²-x-9
C. -X²-X+9
D.X²+9

Answer 1

Explanation:

For question 2, simplify the polynomial 3x²+6-2x+5x-4x²+9 by combining like terms:

3x² - 4x² + 5x + 6 + 9 = -x² + 5x + 15

Therefore, the simplified polynomial is: D. -x² + 7x + 15

For question 3, simplify the polynomial 2X²+6X-7X+8=3X²+1 by moving all terms to one side and combining like terms:

2X² + 6X - 7X - 3X² = 1 - 8

-X² - X - 7 = 0

Therefore, the simplified polynomial is: C. -X² - X + 9
