Question

2. Factorise the expressions and divide them as directed:
(iii) 3(x⁴-256)÷(x²+16)
​

Answer 1

Answer:

3x^2-48

Step-by-step explanation:

3(x^4-256)÷(x^2+16)

3x^4-768÷z^2+16

3x^2-48

Answer 2

Step-by-step explanation:

3(x⁴-256) / (x²+16)

= 3[x⁴-4⁴] / x²+4²

= 3 [(x²)²- (4²)²] / x²+4²

= 3 [(x²+4²)(x²-4²)] / x²+4²

= 3 (x²- 4²)

= 3x² -48
