文字表达式：两个数的和与这两个数的差的积等于这两个数的平方差。此即平方差公式[2] 。公式特征：左边为两个数的和乘以这两个数的差，即右边是两个二项式的积，在这两个二项式中有一项(a)完全相同，另一项(b与-b)互为相反数；右边为这两个数的平方差即右边是完全相同的项的平方减去符号相反...
Move a formula to another location Unlike copying a formula, when you move a formula to another location in the same or another worksheet, the cell references in the formula don’t change, regardless of what type of cell reference you used. ...
a方-b方是平方差公式，a-b=(a+b)(a-b)。两个数的和与这两个数的差的积等于这两个数的平方差。此即平方差公式。平方差公式（formulaforthedifferenceofsquare）是指两个数的和与这两个数差的积，等于这两个数的平方差。公式中字母的不仅可代表具体的数字、字母、单项式或多项式等代数式。在...
表达方式不同。完全平方差公式是(a-b)²=a²-2ab+b²平方差公式是a²-b²=(a+b)(a-b)
