Question

simplify using identies (8a-3)(8a-3)​

Answer 1

Answer:

(8a-9b)(64a^2+72ab+81b^2)

Step-by-step explanation:

8a^3-9b^3)=(8a-9b)(8a^2+(8a)(9b)+9b^2)

=(8a-9b)(64a^2+72ab+81b^2)

Answer 2

Answer:

(8a-3)(8a-3)​

Step-by-step explanation:

 Simplifying using identity (a−b) 2  =a  2  −2ab+b2

(8a-3)(8a-3)​=  (8a)^2   −2×8a×3+3^2

 => 64a2-48a+9
