Hello haohaoxNienie!

\huge \boxed{\mathbb{QUESTION} \downarrow}

Use the remainder theorem to determine whether x = - 4 is a solution of x⁶ + 5x⁵ + 5x⁴ + 5x³ + 2x² - 10x - 8.

\large \boxed{\mathbb{ANSWER\: WITH\: EXPLANATION} \downarrow}

<em><u>Refer </u></em><em><u>to</u></em><em><u> the</u></em><em><u> attached</u></em><em><u> picture</u></em><em><u>.</u></em>

<h3><u>Steps </u><u>:</u><u>-</u></h3>
  1. First find the divisor using the given information (x = - 4).
  2. Now, divide x⁶ + 5x⁵ + 5x⁴ + 5x³ + 2x² - 10x - 8 by x + 4.
  3. We'll get the remainder as 0.
  4. Using the remainder theorem & solving it, we'll get LHS & RHS as 0.
  5. Hence proved.

<u>Answer</u><u> </u><u>:</u><u>-</u><u> </u>Yes, x = - 4 is a solution of x⁶ + 5x⁵ + 5x⁴ + 5x³ + 2x² - 10x - 8.

Help me to solve thisssss​
m_a_m_a [10]

Answer:

(a + 3)

Step-by-step explanation:

a³ - 9a = a(a² - 9) = a(a + 3)(a - 3)

a² + a - 6 = (a - 2)(a + 3)

a⁴ + 27a = a(a³ + 27) = a(a - 3)(a² + 6a + 9) = a(a - 3)(a + 3)(a + 3)

HCF = (a + 3)

Hope it helps.
