Question

fatore as expressões.
a)x^3-x^2-xy
b)a+b+(a+b)x
c)4x^2-12x+9
d)36a^2+60ab+25b^2 e)x^2-6x-16
f)m^2-100
g)ax-y-x+ay

Answer 1

a)x^3-x^2-xy ==> x (x^2 - x -  y)

b) 1(a+b)+(a+b)x =  (1+x)(a+b)

c)4x^2-12x+9 = (2x - 3)^2

d)36a^2+60ab+25b^2

e)x^2-6x-16 = (x - 8)(x+2) 

f)m^2-100 = (m+10)(m-10)

g)ax-y-x+ay = ax - x + ay -y ==> x(a-1)+y(a-1) ==> (x+y)(a-1) 

Answer 2

1(a+b)+(a+b)x=(1+x)(a+B)
