If x is an integer, then which of the following is the product of the next two integers greater than 2(x + 1)? 4x*x + 14x + 12 4x*x + 12 x*x + 14x
If x is an integer, then which of the following is the product of the next two integers greater than 2(x + 1)?
4x*x + 14x + 12
4x*x + 12
x*x + 14x + 12
x*x + x+ 12
4x*x + 14x
答案:4×2+14x+12,2(x+1)之后的两个整数分别是2x+3与2x+4,相乘即可得到正确答案,这里需要注意的一点是原题中product的用法,在这里的意思是两个数的乘积。
