Find the Common Factor in 2x²+7x: Step-by-Step Factorization

Question

The expression 2x2+7x 2x^2+7x is factorised into its basic terms:

2xx+7x 2\cdot x\cdot x+7\cdot x

Take out the common factor from the factorised expression.

Step-by-Step Solution

To solve this problem, we'll focus on finding the greatest common factor of the expression 2x2+7x 2x^2 + 7x .

  • Step 1: Identify the given expression 2x2+7x 2x^2 + 7x .
  • Step 2: Look for common factors:
    • In the term 2x2 2x^2 , the factors are 2 2 , x x , and x x .
    • In the term 7x 7x , the factors are 7 7 and x x .
  • Step 3: Notice that the common factor here is x x , as it is present in both terms.
  • Step 4: Factor x x out of each term in the expression:
    2x2+7x=x(2x)+x(7)=x(2x+7) 2x^2 + 7x = x(2x) + x(7) = x(2x + 7)

Therefore, the expression 2x2+7x 2x^2 + 7x can be factorized as x(2x+7) x(2x + 7) .

This corresponds to choice 3, which is x(2x+7) x(2 \cdot x + 7) .

The factorized expression is x(2x+7) x(2x + 7) .

Answer

x(2x+7) x\left(2\cdot x+7\right)
