factor : 2x^2+5x+14x+35

1 answer

To factor the expression \( 2x^2 + 5x + 14x + 35 \), we can first combine the like terms:

\[ 2x^2 + (5x + 14x) + 35 = 2x^2 + 19x + 35 \]

Next, we need to factor the quadratic expression \( 2x^2 + 19x + 35 \). We are looking for two numbers that multiply to \( 2 \times 35 = 70 \) and add to \( 19 \).

The two numbers that fit these criteria are \( 14 \) and \( 5 \).

Now, we can rewrite the expression:

\[ 2x^2 + 14x + 5x + 35 \]

Next, we can group the terms:

\[ (2x^2 + 14x) + (5x + 35) \]

Now we factor out the common factors from each group:

\[ 2x(x + 7) + 5(x + 7) \]

Now we notice that \( (x + 7) \) is a common factor:

\[ (2x + 5)(x + 7) \]

So, the factored form of the expression \( 2x^2 + 19x + 35 \) is:

\[ \boxed{(2x + 5)(x + 7)} \]
