tolong bagi yang bisa yaa. thankyouu:)

limit (x^2 - 2x - 8)/(Vx - 2)
limit (x^2- 2x -8)(Vx +2) / (Vx- 2)(Vx + 2)
limit (x^2 -2x - 8)(Vx +2 ) / (x -4)
limit (x -4)(x +2)(Vx + 2) / (x -4)
limit (x + 2)(Vx + 2)
= (4 + 2)(V4 + 2)
= (6)(4)
= 24
2) limit (2x -3)(-x + 5) /(-2x^2 + x + 5)
limit (-2x^2 +13x - 15) / (-2x^2 + x + 5)
= -2/-2
= 1
