Answer:
<h2><u><em>
2x² +5x - 12</em></u></h2>
Step-by-step explanation:
(2x - 3) * (x + 4) =
2x² + 8x - 3x - 12 =
<u><em>2x² +5x - 12</em></u>
(2x100) (3x10) (2x1) / (4x1)
(10) minus (5-1/2) = 4-1/2 .
We will determine the length of the segment DF as follows:
*We have that the triangles are similar, and therefore the following is true:
![\frac{2}{1.34}=\frac{4}{DF}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B1.34%7D%3D%5Cfrac%7B4%7D%7BDF%7D)
Now, we solve for DF:
![\Rightarrow DF=\frac{1.34\cdot4}{2}\Rightarrow DF=2.68](https://tex.z-dn.net/?f=%5CRightarrow%20DF%3D%5Cfrac%7B1.34%5Ccdot4%7D%7B2%7D%5CRightarrow%20DF%3D2.68)
From this, we have that the length of the segment DF equals 2.68 units.
