Question

Fatore as expressões :
a) x²+5x=
b)4x²-12x+9=
c)4x²-9=
d) a6-5a5+6a³=
f)64y²+80y+25=
g)a³b²+a²b³=
g)m6-1=

Answer 1

a) x²+5x = x(x+5)
b) 4x²-12x+9= (2x-3)²
c) 4x²-9= (2x+3)(2x-3)
d) a^6-5a^5+6a^3= a^3( a^3 - 5a^2 + 6)
e)  64y²+80+25 = (8y+5)²
f) a³b² +a²b³ = a²b² ( a+b) 
g) m^6 - 1 = (m^3 + 1 )( m^3 -1) 
^  → quer dizer ''elevado a ''

Answer 2

a) x(x+5)
b) (2x-3)²
c) (2x-3) (2x+3)
d) a(6-5+6a²)
f) (8y+5)²
g)(b².a²) (a.b) (não tenho certeza)
g) (m3 + 1 )( m3 -1)
