Question

use suitable identities to find the products : (x^2-4)(x^2+4)

answer please​

Answer 1

Answer:

(a+b)(a-b)=a^2-b^2 is suitable identities.

Step-by-step explanation:

(x^2-4)(x^2+4)=(x^2)^2-(4)^2

=x^4-16

Answer 2

Answer:

x⁴-16

Step-by-step explanation:

(x²-4) (x²+4)

using Identity, (a+b) (a-b) = a²-b²

(x²-4) (x²+4) = x⁴-4² = x⁴-16
