Question

Me ajudem gente é pra amanhã, e eu não sei responder nada

Answer 1

a) 4x⁴y²-6x³+8x²y⁴=

m.d.c.(4,6,8)=2

m.d.c.(x⁴,x³,x²)=x²

m.d.c.(y⁴,y³,y²)=y²

b) 18ab³c²+27a³b⁴c³-9a²b⁵c⁴-45a²b³c²

m.d.c.(18,27,9.45)=9

m.d.c.(a³,a²,a)=a

m.d.c.(b⁵,b⁴,b³)=b³

m.d.c.(c⁴,c³,c²)=c²

c) a.(a+3b)-2c.(a+3b)=

(a-2c).(a+3b)

d) x².(x-3y²)-2y.(x-3y²)=

(x²-2y).(x-3y²)

e) (x²+z)+xy.(x²+z)-z.(x²+z)=

(x²+z).(1+xy-z)

f) a⁴b⁶-9c²=

√(a⁴b⁶)=a²b³

√(9c²)3c

(a²b³+3c).(a²b³3c

g) 9a⁴-b⁴

√(9a⁴)=3a²

√(b⁴=b²

(3a²+b²).(3a²-b²

h) 25x⁶+10x³y+y²=

√(25x⁶)=5x³

√(y²)=y

(5x³+y).(5x³+y)

i) 49x⁴+14x²+1=

√(49x4)=7x²

√(1)=1

(7x²+1).(7x2+1)

j) 20a²b²-2a⁴-50b⁴=

-2.(-10a²b²+a4+25b⁴)=

-2.(a⁴-10a²b²+25b⁴)=

√(a⁴)=a²

√(25b⁴)=5b²

-2.(a²+5b²).(a²+5b²)
