Question

一道数学题目！！！平方差的。。。谢谢！

(根号6+根号3-根号2)的平方-(根号6-根号3-根号2)的平方

Answer 1

=(根号6+根号3-根号2+根号6-根号3-根号2）（根模明空号6+根号3-根号2根号6+根号旦瞎3+根号2)
=(2根号6-2根号2)(2根号6+2根号3)
=4(6+根号18-根号12-根号槐亏6)
=4(6+根号2-根号6)
=24+4(根号2-根号6)

Answer 2

(根号6+根号3-根号2)的平游缺方-(根号6-根号3-根号2)的平方
=(根号6+根号3-根号2+根号6-根号3-根散茄号2)(根号6+根号3-根神掘辩号2 - 根号6+根号3+根号2)
=(2根号6-2根号3)×2根号3
=12根号2-12

Answer 3

你用这个公式看看

(a+b+c)平方=a平方+b平方+c平方+2ab+2ac+2bc

Answer 4

(√6+√3-√2)²-(√6-√3-√2)²
=(√6+√3-√2+√6-√3-√2)(√6+√3-√2-√6+√3+√咐森顷2)
=2(√6-√衡陆春返2)*2√3
=12√2-4√6

Answer 5

(√6+√3-√2) ²－(√6-√3-√2)²
=[(√6+√3-√2) +(√6-√3-√2)][(√6+√3-√2) -(√6-√3-√2)]
=(√6+√3-√扰橡2+√6-√陪李族3-√2)(√6+√3-√2 -√6+√芦弊3+√2)
= (2√6-2√2)(2√3)
=(2√6)×(2√3)-(2√2)×(2√3)
=4√18-4√6
=12√2-4√6
