Answer:
- 11x² + 4x + 14
Step-by-step explanation:
Given
(9 - 3x²) + (- 8x² + 4x + 5) ← distribute both parenthesis by 1
= 9 - 3x² - 8x² + 4x + 5 ← collect like terms
= - 11x² + 4x + 14 ← sum of the polynomials
Answer:
Yes
Step-by-step explanation:
If we multiply them out, we get 6x + 2.4 for the first one and 6x + 2.4 for the second one, therefore they are the same.
B. If you were to solve for x, the values would be x=1.5275 and x=-1.5275.
