The factor is

(x + 4) (x + 3)

x + 4 = 0         x + 3 = 0

x = -4              x = -3

x 2 + 7x + 12. Factor the trinomial to find the length and width of the rectangle.

 

\(x ^2 + 7x + 12\\ =x^2+3x+4x+12\\=x(x+3)+4(x+3)\\\color{blue}=(x+3)(x+4)\)

 

The length of the rectangle is 4 units.

 

The width of the rectangle is 3 units.
