Factoriza la diferencia de cubos 1) 8x³ -64
2) 125x³- 64y{6}
3) 8a³- 27b³
4) 27a³- 27b³

The first one will be equal 2

Because

Oh sorry i read the question wrongly i thought you wanted the value of x

Step-by-step explanation:

main formula used

a³-b³=(a-b)(a²+ab+b²)

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
