Question

find the product using the identity (a+b)(a-b)=a²-b² (x+p)(x-p)​

Answer 1

Answer:

x²-p² is the answer

Step-by-step explanation:

(x+p) (x-p)

since (a+b)(a-b)=a²-b²

so,(x)²-(p)²

Therefore x²-p²

Answer 2

Step-by-step explanation:

Answer:

(27 {x}^{3} - 3 \times 9 {x}^{2} \times 4y + 3 \times 3x \times 16 {y}^{2} - 64 {y}^{3} ) - (27 {x}^{3} + 3 \times 9 {x}^{2} \times 4y + 3 \times 3x \times 16 {y}^{2} + 64 {y}^{3} ) = 2( - 108 {x}^{2} y - 64 {y}^{3} ) = - 216 {x}^{2} y - 128 {y}^{3}(27x
