Question

simplifique os polinomios:
a) 5x²y³- 4x²+ 3x(x-2) - 2x²y³+3+x²
b) x(2x+3y)-11(xy+2y)+2x²

Answer 1

5x²y³ - 4x² + 3x(x - 2) - 2x²y³ + 3 + x² = 
5x²y³ - 4x² + 3x² - 6x - 2x²y³ + 3 + x² =
5x²y³ - 2x²y³ - 4x² + 3x² + x² - 6x + 3 =
3x²y³ - 6x + 3

--------------------------------------------------------------------------

x(2x + 3y) - 11(xy + 2y) + 2x² =
2x² + 3xy - 11xy - 22y + 2x² = 
2x² + 2x² + 3xy - 11xy - 22y =
4x² - 8xy - 22y
