Answer 1

Answer:

(ax² + 1)(a + x)

Step-by-step explanation:

⇒ (a²x² + ax³) + (x + a)

⇒ ax² (a+x) + 1(a+x)

⇒ (ax² + 1)(a + x)

Hope this helps.....

Answer 2

${a}^{2} {x}^{2} + (a {x}^{2} + 1)x + a$

$= {a}^{2} {x}^{2} + a {x}^{3} + x + a$

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

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

$⟹x + a = 0 \: \: and \: \: a {x}^{2} + 1 = 0$

$⟹x = - a \: (ans)$
