^2-oznacza do kwadratu
a) (ax + 4)² = a²x² + 4ax + 4ax + 16 = a²x² + 8ax + 16
b) (ax - 4)² = a²x² - 4ax - 4ax + 16 = a²x² - 8ax + 16
c) (ax-4)(ax+4) = a²x² + 4ax - 4ax - 16 = a²x² - 16
d) ( √2 - 2x)² = 2 - 2√2x - 2√2x + 4x² = 2 + 4x² - 4√2x
e) (√2 + 2x)² = 2 + 2√2x + 2√2x + 4x² = 2 + 4x² + 4√2x
f) (√2 - 2x)(√2 + 2x) = 2 + 2√2x - 2√2x - 4x² = 2 - 4x²
