Factorise: 3x5 – 48x3 – InterviewSolution

1.	Factorise: 3x5 – 48x3
Answer» 3x⁵ – 48x³ can be written as 3x³(x² – 16) By using the formula a² – b² = (a+b) (a-b) Now solving for the above equation 3x³(x² – 16) = 3x³((x)² – (4)²) = 3x³(x+4) (x-4)

Factorise: 3x5 – 48x3

Answer»

3x⁵ – 48x³ can be written as 3x³(x² – 16)

By using the formula a² – b² = (a+b) (a-b)

Now solving for the above equation

3x³(x² – 16)

= 3x³((x)² – (4)²)

= 3x³(x+4) (x-4)
