Question

Descompuneti in factori:
36x²-x⁴=
81-9x⁴=
49x²-100=
a(x-5)+b(x-5)-c(x-5)=
3x²(y-5)-6x(y-5)=
Daca puteti sa-mi raspundeti cat mai repede posibil!!!

Answer 1

x"2(36-x"2)=x"2(6-x)(6+x)
81-9x"4=9"2-(9x"2)"2=(9-9x"2)(9+9x"2)=9(1-x"2)(1+x"2)
49x"2-100=49x"2-10"2=(49x-10)(49x+10)
=(x-5)(a+b-c)
(y-5)(3x"2-6x)
