Question

Which identity, do we use to factorize 25x2 + 40x + 16 a) ( + ) 2 = a2 + 2ab + b 2 b) ( − ) 2 = a 2 - 2ab + b2 c) ( + )( − ) = a 2 – b 2 d) ( + )( + ) = x 2 + ( a+b) x + ab ​

Answer 1

Answer:

Write ten homophones with their meaning and make sentences from them.

Answer 2

Answer:

Using (a−b)2= a2−2ab+b2

To Compute (3x−5y)2

(3x)2−2(3x×5y)+(5y)2

9x2−2(15xy)+25y2

Solution - 9x2−30xy+25y2
