Simplify completely x? + 2x - 120
+
6x + 60
X-2 .(2 points)
X-1
6(x+6)
X-2
6(x+10)
X-2
6(x+12)
X-1
3(x+12)

Answer 1

`(x^(2)-100 )/(x^(2)+2x-120 )+(6x+60)/(x-2)\\\\\\=((x-10)(x+10))/((x-10)(x+12))+(6x+60)/(x-2)\\\\=(x+10)/(x+12)+(6(x+10))/(x-2)\\\\=(x+10((1)/(x+12)+(6)/(x-2))\\\\=(x+10)((x-2+6x+6.12)/((x+12)(x-2)))\\\\=(x+10)((7x+70)/((x+12)(x-2)))\\=(7(x+10)^(2) )/((x+12)(x-2))`

It's the simplest form I can make
