Rozwiązanie:
a) -1/4 a^2 - 20 ab + 1/4b^2
b) (5a+5b - b+a )/2= (6a + 4b) /2 = 3a + 2b
c)(8a - 4 + 4a)/4 = (12a - 4) /4 = 3a -1
d) (2a +2b -2 - a + b)/3 = (a + 3b -2 )/3 = 1/3 a +b -2/3
a) 1/3 + 5a
b) 5b - 2a
c) ( 8ab + ab + 3a^2 ) /3a = ( 9ab + 3a^2 )/3a = 3b + a
d) 14c +(2x/c)/0,5 = 14c + 4x/c
e) (16x^2 + 8x - 5x^2 - 10x)/x = (11x^2 - 2x)/x = x(11x -2)/x = 11x -2
f) (20 x^2 + 8xy - 20 x^2 - 8x^2*y)/xy = (8xy - 8x^2*y)/xy = 8 - 8x = 8(1 - x)
