1.	Factorize the following a^4+a^2+1
Answer» Step-by-step EXPLANATION: $a {}^{4} + a {}^{2} + 1 \\ = a {}^{4 } + 2a {}^{2} + 1 - a {}^{2} \\ = (a {}^{2} + 1) {}^{2} - (a) {}^{2} \\ = (a {}^{2} + 1 + a)(a {}^{2} + 1 - a) \\ = (a {}^{2} + a + 1)(a {}^{2} - a + 1$

Answer»

Step-by-step EXPLANATION:

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