Question

Polinômios: Adição ou subtração

Answer 1

a
(2xy)⁶ - ( 4x³y³)² + ( 2x²y²)³ - 3x² *(2y)⁶
64x⁶y⁶ - 16x⁶y⁶ + 8x⁶y⁶ - 3x²  * (64y⁶ )
64x⁶y⁶ - 16x⁶y⁶ + 8x⁶y⁶ - 192x²y⁶
56x⁶y⁶ - 192x²y⁶  =8x²y⁶( 7x⁴ - 24 ) ****
b
3x⁴y⁴ - ( 5x²y²)² + (2x²)²* y⁴ + 5x²y⁴ =
3x⁴y⁴ - 25x⁴y⁴ + 4x⁴ * y⁴ + 5x²y⁴ =
3x⁴y⁴ - 25x⁴y⁴ + 4x⁴y⁴ + 5x²y⁴
-18x⁴y⁴ + 5x²y⁴ =
18x⁴y⁴ - 5x²y⁴ =   x²y⁴ ( 18x² - 5 ) ****

c
4x + 5x - ( -3x + 5y - 6 ) - ( 4x + 3y) + 8 =
4x + 5x  + 3x - 5y + 6 - 4x - 3y + 8 =
8x - 8y  + 14 =
4x - 4y + 7 ****

d
( xy³ - x ) + ( xy³ + x) - ( 2xy³ + 1 ) + 7 =
( xy³ - x) + ( xy³ + x) - (2xy³ + 1 ) = - 1 + 7 = 6
