The area of a rectangle is equation to its length multiplied by its width:
Substituting what we know:
Therefore, the equation for the area of the rectangle is `8x^2+10x-3`
`A= l xx w=(4x-1)(2x+3)=8x^2+12x-2x-3=8x^2+10x-3`
The Area value graph. Note the negative value for `-3/2 <= x <= 1/4` are discarged for neagtive values for area have no meaning.
