f'(x) =[(t² – 1)'(t² + t – 2)-(t² – 1)(t² + t – 2)’]/(t² + t – 2)²
f'(x) =[2t(t² + t – 2)-(t² – 1)(2t + 1)]/(t² + t – 2)²
f'(x) =[2t³+ 2t² – 4t)-(2t³ -2t +t²- 1)]/(t² + t – 2)²
f'(x) =[2t³+ 2t² – 4t-2t³ +2t -t²+1)]/(t² + t – 2)²
f'(x) =[t² -2t+1]/(t² + t – 2)²
f'(x) =[t-1]²/(t^4+2t³-3t² -4 t +4)
f'(x) =[t-1]²/(t³+3t² -4 )(t -1)
f'(x) =[t-1]/(t³+3t² -4 )
