Solve (A-B)2=A2+2AB-B2

Evaluate

(A - B) \times 2 = A \times 2 + 2 A B - B \times 2

Multiply the terms

2 (A - B) = A \times 2 + 2 A B - B \times 2

Simplify

More Steps

2 (A - B) = 2 A + 2 A B - 2 B

Rewrite the expression

2 (A - B) = 2 A + 2 B A - 2 B

Collect like terms by calculating the sum or difference of their coefficients

2 (A - B) = (2 + 2 B) A - 2 B

Expand the expression

2 A - 2 B = (2 + 2 B) A - 2 B

Expand the expression

2 A - 2 B = 2 A + 2 B A - 2 B

Cancel equal terms on both sides of the expression

0 = 2 B A

Swap the sides of the equation

2 B A = 0

Solution

A = 0
