x+4=2x+1

-x -x

4=x+1

-1

3=x

3+4 = 7

2(3)+1 = 7

7+7=14

BC = 14

Hey can you please help me posted picture of question

Common factor is such a term which can be taken out common from each term of the expression.

If you observe the given expression, 2x can be taken out common leaving the expression which cannot be factored any further.

14x² - 12x
= 2x (7x - 6)

So 2x is the common factor. The answer to this question is option C

6 Which expression is equivalent to 2x2 + 7x +4?

dlinn [17]

Option J is correct.

Step-by-step explanation:

We need to find the expression equivalent to $2x^2 + 7x +4$

Finding the equivalent expression:

$2x^2 + 7x +4$

We check all the expressions given:

Option F: (2x-1)(x+4)

Multiplying both terms:

$2x(x+4)-1(x+4)\\=2x^2+8x-x-4\\=2x^2+7x-4$

This expression is not equivalent to $2x^2 + 7x +4$ , So, Option F is incorrect.

Option G: (2x+1)(x-4)

Multiplying both terms:

$2x(x-4)+1(x-4)\\=2x^2-8x+x-4\\=2x^2-7x-4$

This expression is not equivalent to $2x^2 + 7x +4$ , So, Option G is incorrect.

Option H: (2x+1)(x+4)

Multiplying both terms:

$2x(x+4)+1(x+4)\\=2x^2+8x+x+4\\=2x^2+9x+4$

This expression is not equivalent to $2x^2 + 7x +4$ , So, Option H is incorrect.

Option J: None of these

So, Option J is correct.
