Doprowadź do najprostszej postaci. a) (6x-3)^+(5x+2)^ b) (4x+3)^ - (3x+2)^ c) (5x-1)^ + (4x+5)^ d) (7x-3)^ - (6x+2)^ e) (3x-8)^ - (3x+8)^.
Proszę o szybką odp. potrzebne na dziś.

a) (6x-3)²+(5x+2)² = 36x² - 36x + 9 + 25x² + 20x + 4 = 61x² -16x +13
b) (4x+3)² - (3x+2)² = 16x² + 24x + 9 – 9x² - 12x – 4 = 7x² +12x +5
c) (5x-1)²+ (4x+5)² = 25x² - 10x + 1 + 16x² + 40x + 25 = 41x² + 30x +26
d) (7x-3)²- (6x+2)² = 49x² - 42x + 9 - 36x² - 24x – 4 = 13x² -66x + 5
e) (3x-8)² - (3x+8)² = 9x² - 48x + 64 – 9x² - 48x – 64 = -96x
