Factor 2x^2+11x+5

$2 x^{2} + 11 x + 5$

For a polynomial of the form $a x^{2} + b x + c$ , rewrite the middle term as a sum of two terms whose product is $a \cdot c = 2 \cdot 5 = 10$ and whose sum is $b = 11$ .

Factor $11$ out of $11 x$ .

$2 x^{2} + 11 (x) + 5$

Rewrite $11$ as $1$ plus $10$

$2 x^{2} + (1 + 10) x + 5$

Apply the distributive property.

$2 x^{2} + 1 x + 10 x + 5$

Multiply $x$ by $1$ .

$2 x^{2} + x + 10 x + 5$
