Question

simplify (t+s^2)(t^2-s)​

Answer 1

$(t + s ^{2} )(t - s ^{2} )$

$(t) ^{2} - (s ^{2} )^{2}$

$t ^{2} - s ^{4}$

Answer 2

$(t + {s}^{2} )( {t}^{2} - s)$

$= t \times {t}^{2} + t \times (- s) + {s}^{2} \times {t}^{2} + {s}^{2} ( - s)$

${t}^{3} - st + {s}^{2} {t}^{2} - {s}^{3}$

Hope it helps ✌️
