A = 3x² - 5x + 2
B = 3x² + 5x - 2
----------------------
a)
A + B = 3x² - 5x + 2 + 3x² + 5x - 2
A + B = 3x² + 3x² - 5x + 5x + 2 - 2
A + B = 6x² + 0 + 0
A + B = 6x²
-------------------
b)
A - B = 3x² - 5x + 2 - (3x² + 5x - 2)
A - B = 3x² - 5x + 2 - 3x² - 5x + 2
A - B = 3x² - 3x² - 5x - 5x + 2 + 2
A - B = 0 - 10x + 4
A - B = - 10x + 4
-------------------------------
c)
B + A = 3x² + 5x - 2 + 3x² - 5x + 2
B + A = 3x² + 3x² + 5x - 5x - 2 + 2
B + A = 6x² + 0 + 0
B + A = 6x²
-------------------------
d)
B - A = 3x² + 5x - 2 - (3x² - 5x + 2)
B - A = 3x² + 5x - 2 - 3x² + 5x - 2
B - A = 3x² - 3x² + 5x + 5x - 2 - 2
B - A = 0 + 10x - 4
B - A = 10x - 4
