Question 717388
simplify the following : 
3X^2-4x-15/ x^2-4x+3
Factor:
[3x^2-9x+5x-15] / [(x-3)(x-1)]
-----
[3x(x-3)+5(x-3)] / [(x-3)(x-1)]
-----
= [(x-3)(3x+5)] / [(x-3)(x-1)]
-----
= (3x+5)/(x-1)
===========================

X^2Y^3/X^-3y^5
---------
= (x^2/x^-3)(y^3/y^5)
------
= (x^5)(1/y^2)
----
= x^5/y^2
===========================
 
(5x^3y^0)^-2
----
= 1/(25x^6)
===========================
 
What's the factor of the following trinomial: 
2X^2+5x-12
----
= 2x^2+8x-3x-12
----
= 2x(x+4)-3(x+4)
----
= (x+4)(2x-3)
