Question

multiply ( x + a ) ^ { 2 } - ( x - b ) ^ { 2 } + x ^ { 2 } + ( a - b ) x - a b , by ( a + b )
( by using algebraic identities)​

Answer 1

Answer:

( x + a ) ^ { 2 } - ( x - b ) ^ { 2 } + x ^ { 2 } + ( a - b ) x - a b , by ( a + b )

Answer 2

Step-by-step explanation:

The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube.
