Question

Evaluate :
(i) (x - 2) (x + 2) (x2 + 4)​

Answer 1

Answer:

X⁴-16

Step-by-step explanation:

(X-2)(X+2)(X2+4)

(a+b)(a-b)=a²-b²

(X²-2²)(X²+4)

(X²-4)(X²+4)

Again apply same formula,,

(X²)²-4²

X⁴-16

If given eqqual to zero..

Then

x⁴=16

X⁴=2⁴

X=2

HOPE IT HELPS FRND!!!

Answer 2

Step-by-step explanation:

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

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

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

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

=x^4-16
