Answer 1

Step-by-step explanation:

${\large{\mathfrak{\underline{\pink{Required \: Answer :}}}}}$

${\bold{\mathrm{: \: ⟹ \: \: \: \: \: x⁴ \: + \: 18x³ \: + \: 99x² \: + \: 162x \: + \: 56}}}$

${\Large{\mathbf{\underline{\orange{Question :-}}}}}$

Let's resolve into factors :

x(x + 3)(x + 6)(x + 9) + 56

$\\ {\Large{\mathbf{\underline{\orange{Solution :-}}}}}$

Given :

x(x + 3)(x + 6)(x + 9) + 56

Let's factorise :

➠(x + 6)(x + 9) • x² + 3x(x + 6)(x + 9) + 56

➠ (x + 9) • x³ + 6(x + 9) • x² + 3x(x + 6)(x + 9) + 56

➠ x⁴ + 9x³ + 6(x + 9) • x² + 3x(x + 6)(x + 9) + 56

➠ x⁴ + 9x³ + 6x³ + 54x² + 3x(x + 6)(x + 9) + 56

➠ x⁴ + 15x³ + 54x² + 3x(x + 6)(x + 9) + 56

➠ x⁴ + 15x³ + 54x² + 3(x + 9) • x² + 18x(x + 9) + 56

➠ x⁴ + 15x³ + 54x² + 3x³ + 27x² + 18x(x + 9) + 56

➠ x⁴ + 15x³ + 54x² + 3x³ + 27x² + 18x² + 162x + 56

➠ x⁴ + 15x³ + 54x² + 3x³ + 45x² + 162x + 56

➠ x⁴ + 18x³ + 54x² + 45x² + 162x + 56

➠ x⁴ + 18x³ + 99x² + 162x + 56
