$x^{2} + 12 x + 35$ $x^2 +12x +35$

Multiply each term in the first bracket by each term in the second bracket.

Commonly called the FOIL rule..Multiply the " Firsts, Outers Inners LAsts",

$x^{2} + 5 x + 7 x + 35$ $x^2 + 5x +7x +35$

The two middle terms can be added.

$x^{2} + 12 x + 35$ $x^2 +12x +35$
