Yg bisa jawab plis yg e. sama f.
(e)
=[ (x – 5) (x + 3) ] / [ (x – 5)(x+5) ] × [(x+5) (x-1)] / [(x+3) (x-1)]
= [(x-5)(x-5) (x+3) ( x-1) ] / [ (x-5) (x+5) (x-1) ]
= (x-5) / (x + 5)
(f)
=[(x+7)(2x-3)] / [(2x-3)(2x+3)] × [(x+4)(2x+3)] / [(x+7)(x-2)]
= [ (x+7)(2x-3)(x+4)(2x+3) ] / [ (2x-3)(2x+3)(x+7)(x-2)]
= (x+4) / (x-2)
