Answer:
-21x² + 8x + 2
Step-by-step explanation:
Addition of two polynomials:
Like terms have same variable with same power. Combine like terms.
(-16x² & -5x² are like terms ; 10x and (-2x) are like terms ; (1 and 1 are constants)
-16x² + 10x + 1 + (-5x² - 2x + 1) = -16x² + 10x + 1 -5x² - 2x + 1
= -16x² - 5x² + 10x - 2x + 1 + 1
= -21x² + 8x + 2
