Question

Amplificati cu x-2 fractiile

Answer 1

a) 2/3 amp. cu x-2 = 2(x-2) / 3(x-2) = (2x-4) / (3x-6)

b) nu merge pentru ca x-2#0 , x #2

c) nu merge

d) 2x³ / (x²+1) amp. cu x-2 = (2x⁴-4x³) / (x³-2x²+x-2)

e) (x-1) / (x²+2) amp. cu x-2 = (x-1)(x-2) / (x²+2)(x-2) = (x²-2x-x+2) / (x³-2x²+2x-4) = (x²-3x+2) / (x³-2x²+2x-4)
