if value of x is 1 then answer is 0

Answer 2

factorize numerator
${x}^{3} + {x}^{2} - 2 \\ we \: get \: (x - 1) \times ( {x}^{2} + 2x + 2) \\ limit_{x = 1}( {x}^{3} + {x}^{2} - 2 ) \div (x - 1) \\ = limit_{x = 1}(\frac{ (x - 1) \times ( {x}^{2} + 2x + 2) } {(x - 1}) \\ \\ = {1}^{2} + 2(1) + 2 \\ 1 + 2 + 2 = 5$
