Question

como resolve, Fatore as expressões:
A) 7X +X ² =
B) 8x -3x y +8 -3y =
C) 1 -100A² =
D) M³ -M =

Answer 1

A) 7X +X ² = x-(7+x)  

                   B) 8x -3x y +8 -3y = X.(8-3Y)+8-3Y

C) 1 -100A² = (1+10A ).(1.10A)         (8-3Y)-(X-1)    

D) M³ -M = M².(M-1)

           M.(M-1).( M+1)

Answer 2

Oie, Td Bom?!

>>> Resolvendo as expressões.

a)

$7x + x {}^{2} = x \: . \: (7 + x)$

b)

$8x - 3xy + 8 - 3y = x \: . \: (8 - 3y) + 8 - 3y = (8 - 3y) \: . \: (x + 1)$

c)

$1 - 100a {}^{2} = 1 {}^{2} - 10 {}^{2} a {}^{2} = 1 {}^{2} - (10a) {}^{2} = (1 - 10a) \: . \: (1 + 10a)$

d)

$m {}^{3} - m = m \: . \: (m {}^{2} - 1) = m \: . \: (m - 1) \: . \: (m + 1)$
