Question

(x-2-10)×500+(x-10)(-100x+2400)

Answer 1

问：(x-2-10)×500+(x-10)(-100x+2400)

答：您好，首先，我们可以展开并整理这个表达式： (x-2-10)×500 + (x-10)(-100x+2400) = (x-12)×500 + (x-10)(-100x+2400) = 500x - 6000 + (-100x^2 + 1000x - 24000) + (-1000x + 10000) 接着，我们将相似项合并： = -100x^2 + 500x - 1000x + 1000x + 10000 - 24000 - 6000 = -100x^2 - 19000 所以，给定的表达式化简后为 -100x^2 - 19000。
