Question

Divide (9x3

+ 12x) by 2x.​

Answer 1

Answer:

27 +12x ÷ 2x

Step-by-step explanation:

remainder 27

Answer 2

Given:

The expression:

$\bold { \dfrac{9x^3 + 12x}{2x} }$

What To Find:

We have to divide the given expressions.

How To Find:

To find we have to,

• Cancel the common terms.
• Take out the common factors.
• Use the identities whenever possible.

Solution:

$\rm { \dfrac{9x^3 + 12x}{2x} }$

Cancel 12x and 2x

$\rm { \implies 9x^3 + 6 }$

Take out the common factor ie. 3,

$\rm { \implies 3 (3x^3 + 2) }$

Final Answer:

The answer is 3 (3x³ + 2).

More To Know:

Idenities while factorising any expressions.

• (a + b)² = a² + 2ab + b²
• (a - b)² = a² - 2ab + b²
• (a + b) (a - b) = a² - b²
• (x + a)(x + b) = x² + (a + b) x + ab
• (a + b + c) = a² + b² + c² + 2ab + 2bc + 2ca
• (a + b)³ = a³ + b³ + 3ab (a + b)
