​

Answer 1

Answer:

Step-by-step explanation:

add the following polynomials

5 (5x⁶+2x³-6x²-2) and 6 (-3x⁶ +2x⁵+2x+1)

Solution :

   =  25x⁶ + 10x³ - 30x² - 10 -18x⁶ + 12x⁵ + 12x + 6

   = 25x⁶ -18x⁶ + 12x⁵ + 10x³ - 30x² + 12x -10 + 6

   = 7x⁶ + 12x⁵ + 10x³ - 30x² + 12x - 4

    =  6x⁴-2x³+x²-x+1
