1.	Factorise: 16x5 -144x3
Answer» 16x⁵ -144x³ can be written as 16x³(x² – 9) By using the formula a² – b² = (a+b) (a-b) Now solving for the above equation 16x³(x² – 9) = 16x³((x)² – (3)²) = 16x³(x+3) (x-3)

Answer»

16x⁵ -144x³ can be written as 16x³(x² – 9)

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

Now solving for the above equation

16x³(x² – 9)

= 16x³((x)² – (3)²)

= 16x³(x+3) (x-3)
