Question

Factor: 3x4y3 – 48y3.
​

Answer 1

Answer:

3x⁴y³ - 48y³

3y³ ( x⁴ - 16)

3y³ ( (x²)² - 4²)

3y³ ( x ² - 4) ( x² + 4)

3y³ ( x - 2) ( x + 2) ( x² + 4)

Answer 2

$\huge\underline\mathfrak{\pink{Solution }}$

3x4y3– 48y3.

= 3y3(x4 – 16).

= 3y3[(x2)2 - 42].

= 3y3(x2 + 4)(x2 - 4).

= 3y3(x2 + 4)(x2 - 22).

= 3y3(x2 + 4)(x + 2)(x -2).

Answer: 3y3(x2 + 4)(x + 2)(x -2)
