Factories: 12x 2

We have, 12x 2 – 27 = 3(4x 2 – 9) By using the formula a 2 – b 2 = (a + b)(a – b) We get, 12x 2 – 27 = 3(4x 2 – 9) = 3{(2x) 2 – (3) 2 } = 3(2x + 3)(2x – 3)

Factories:
12x² – 27

We have,

12x² – 27

= 3(4x² – 9)

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

We get,

12x² – 27 = 3(4x² – 9)

= 3{(2x)² – (3)²}

= 3(2x + 3)(2x – 3)
