Zapisz w jak najprostszej postaci:
e) 3x² + 4 + 1/7 * 14x²-21 / 6 =
f) 15p²-9p / 6 - 6 * 1-6p / 4 =
w E ma wyjść : 3 ⅓ x ² + 3 ½
w F ma wyjść : 2,5p² + 7,5p - 1,5.

e) 3x² + 4 + 1/7 * 14x²-21 / 6 =3x² + 4 + ¹/₇ * 14x² - ²¹/₆ = 3x² + 4 + 2x² - 3½ = 5x² + ½
f) 15p²-9p / 6 - 6 * 1-6p / 4 = 15p² - 1½p - 6 - 1½p² = 13,5p² - 1½p - 6
