Question

Am nevoie de ajutor....​

Answer 1

Răspuns:

a) 18ax-6ay+15bx-5by=

=6a(3x-y)+15b(3x-y)=

=(3x-y)(6a+15b)

b) x²+2y+9ax²+18ay=

=x²+9ax²+2y+18ay=

=x²(1+9a)+2y(1+9a)=

=(1+9a)(x²+2y)

c) 10ax+25ay-22bx-55by=

=5a(2x+5y)-11b(2x+5y)=

=(2x+5y)(5a-11b)

d) x³+x²+x+1=

=x²(x+1)+(x+1)=

=(x+1)(x²+1)
