14x-7 over x^2+3x-4 X x^2+6x+8 over 2x^2+5x-3 divided by x^2+2x over x^2+2-3
I need multiple and divide rational expressions and I am lost here. I need some help. Thank you
please note in the last part it is given x^2+2x over x^2+2-3 make the change as x^2+2x over x^2+2x-3
factorise:x^2+3x-4 = x^2+4x-x-4 = x(x+4)-1(x+4)=(x+4).(x-1)
x^2+6x+8 = x^2+4x+2x+8 = x(x+4)+2(x+4)= (x+4).(x+2)
2x^2+5x-3 = 2x^2+6x-x-3 = 2x(x+3)-1(x+3) = (2x-1).(x+3)
x^2+2x = x(x+2)
x^2+2x-3 = x^2+3x-x-3 = x(x+3)-1(x+3) = (x+3).(x-1)

14x-7over(x+4).(x-1)X (x+4).(x+2)over(x+3).(2x-1)divided by x(x+2)over(x+3).(x-1)
7.(2x-1).(x+4).(x+2)/(x+4).(x-1).(x+3).(2x-1)divided by x(x+2)over(x+3).(x-1) 7.(x+2)(x+3).(x-1)/(x-1).x.(x+2).(x+3) = 7/x.
