b) 5x+5y=

c) xy+xz=

d) 5a+10b=

e) 10+15a-5b=

f) 8z-16x-20t=

g) 10a+20b+30c-40d=

h)42a-14x=

i) 25ab+5bac-20ac=

Answer 1

Explicație pas cu pas:

a.2a+2b-2c=2(a+b-c)

b.5x+5y=5(x+y)

c.xy+xz=x(y+z)

d.5a+10b=5(a+2b)

e.10+15a-15b=5(2+3a-3b)

f.8z-16x-20t=4(2z-4x-5t)

g.10a+20b+30c-40d=10(a+2b+3c-4d)

h.42a-14x=14(3a-x)

i.25ab+5bac-20ac=5(5ab+bac-4ac)
