1.

Use a suitable identity to find the product.(x+5)(x+5)

Answer»

Answer:

We KNOW (x−5)(x−5)=(x−5)2

We know (x−5)(x−5)=(x−5)2Now using IDENTITY (x−y)2=x2−2xy+y2

We know (x−5)(x−5)=(x−5)2Now using identity (x−y)2=x2−2xy+y2Here x=x and y=5

We know (x−5)(x−5)=(x−5)2Now using identity (x−y)2=x2−2xy+y2Here x=x and y=5(x−5)2=(x)2−2×x×5+(5)2

We know (x−5)(x−5)=(x−5)2Now using identity (x−y)2=x2−2xy+y2Here x=x and y=5(x−5)2=(x)2−2×x×5+(5)2=x2−10x+25
