Question

a project to verify the expansion formula by using area (a+b)(a-b) =a*2-b*2​

Answer 1

Answer:

word such is all living

Answer 2

Answer:

Step 1: Draw a square ACDF with AC=a units.

Step 2: Cut AB=b units so that BC=(a−b) unts.

Step 3: Complete the squares and rectangle as shown in the diagram.

Step 4: Area of yellow square IDEO= Area of square ACDF− Area of rectangle GOFE− Area of rectangle BCIO− Area of red square ABOG

Therefore, (a−b)

2=a

2−b(a−b)−b(a−b)−b

2= a 2−ab+b

2 −ab+b 2 −b2=a2−2ab+b 2

Hence, geometrically we proved the identity (a−b)2=a 2 −2ab+b2
