A) (3x² + 5x - z) + [(5x² - 3x + z) - (2x² - 2x)]
B) p(x) = g(x) - f(x)
p(x) = (5x² - 3x + z) - (3x² + 5x - z). Find p(x) - m(x)
((5x² - 3x + z) - (3x² + 5x - z)) - (2x² - 2x)
C) 2[f(x) - g(x)] + 3[m(x)]
2[(3x² + 5x - z) - (5x² - 3x + z) + 3[(2x² - 2x)]
**I used parenthesis, so you could tell each function apart. Hope this helps :)
