Question

1 - 8a³ factorize it.

Answer 1

Answer:

$\large\boxed{\sf{(1 - 2a)(1 + 2a + 4 {a}^{2} )}}$

Step-by-step explanation:

To factorise,

$1 - 8 {a}^{3}$

We can further simplify this as,

$= {1}^{3} - 8 {a}^{3}$

Or, we can simplify,

$= {(1)}^{3} - {(2a)}^{3}$

Now, we know that,

• ${x}^{3} - {y}^{3} = (x - y)( {x}^{2} + xy + {y}^{2} )$

Therefore, we will get,

$= (1 - 2a)( {(1)}^{2} + (1)(2a) + {(2a)}^{2} )$

Further simplify, we will get,

$= (1 - 2a)(1 + 2a + 4 {a}^{2} )$

Hence, the factors are :-

$(1 - 2a)(1 + 2a + 4 {a}^{2} )$
