Factories:3x5 – 48x3

We have,3x5 – 48x3= 3x3(x2 – 16)By using the formula a2 – b2 = (a + b)(a – b)We get,3x5 – 48x3 = 3x3(x2 – 16)= 3x3{(x)2 – (4)2}= 3x3(x + 4)(x – 4)

Factories:
3x⁵ – 48x³

We have,

3x⁵ – 48x³

= 3x³(x² – 16)

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

We get,

3x⁵ – 48x³ = 3x³(x² – 16)

= 3x³{(x)² – (4)²}

= 3x³(x + 4)(x – 4)
