探討[math]a^2+b^2[/math]與[math](a+b)^2[/math]的關係。
改動[math]a[/math]和[math]b[/math]的值。將面積是[math]a^2[/math]與[math]b^2[/math]的兩個小正方形放入面積是[math](a+b)^2[/math]的大正方形之內。不重疊部分的面積是多少？你能說出[math]a^2+b^2[/math]與[math](a+b)^2[/math]有甚麼關係嗎？
Investigate the relationship between [math]a^2+b^2[/math] and [math](a+b)^2[/math].
Adjust the value of [math]a[/math] and [math]b[/math]. Put the two small squares onto the large square. What is the area of the non-overlapping region?See what can you tell about the value of [math]a^2+b^2[/math] and [math](a+b)^2[/math].
