Question

Scrieti ca produs de trei factori(rog rezolvarea completa nu doar raspunsul)!!!t(z+ 1)²-t(z-1)², a³- ab², (x²+ 5)² 6(x² + 5), (x²+ y²)²-4x²y² cer rezolvare completa..data trecuta am scris cam neinteles :x

Answer 1

1)  t [z²+2z+1- (z²-2z+1)] = t( z²+2z+1-z²+2z-1) = t * 4z= 4*t*z
2)  a(a²-b²) = a*(a-b)*(a+b)
3) (x²+5) [(x²+5)-6] = (x²+5) (x²-1) = (x²+5)* (x-1)* (x+1)
4) x⁴+2x²y²+y⁴-4x²y²= x⁴-2x²y²+y⁴= (x²-y²) (x²+y²)= (x-y) * (x+y)* (x²+y²)
