10 over x 12 over x34 over 1 0 over 1 find all real solution
10 over x -12 over x-3+4 over 1 =0 over 1
find all real solutions
show work
Solution
(10/x)-(12/(x-3)) +(4/1) =0/1
(10/x)-(12/(x-3)) +4 =0
(10/x)-(12/(x-3)) =0-4
(10(x-3)- 12(x))/(x(x-3)) =-4
(10x-30- 12x) =-4x(x-3)
(-30- 2x) =-4x2+12x
4x2-14x-30=0
2x2-7x-15=0
2x2-10x+3x-15=0
2x(x-5)+3(x-5)=0
(2x+3)(x-5)=0
2x+3=0,x-5=0
x=-3/2 ,x=5
