Question

(x+2) (x-2) (x²+4) ​

Answer 1

Answer:

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

by (a+b) (a-b)=(a^2-b^2)

therefore

(x^2-4)(x^2+4)= (x^4-16)

therefore final answer ---( x^4-16)

Answer 2

Answer:

x⁴-16

Step-by-step explanation:

(x+2) (x-2) (x²+4)

x(x-2) + 2(x-2) (x²+4)

(x²-2x + 2x -4) (x²+4)

(x²-4) (x² +4)

x²(x²+4)-4(x²+4)

x⁴+4x²-4x²-16

=x⁴-16
