Given
The height of a triangle is (2x - 4) and the base is 3x^2- 2x +1.
Explanation
The area of triangle is determined as
[tex]A=\frac{1}{2}\times b\times h[/tex]Substitute the value of base and height.
[tex]\begin{gathered} A=\frac{1}{2}\times(3x^2-2x+1)(2x-4) \\ A=\frac{1}{2}\times(3x^2-2x+1)\times2(x-2) \\ A=(3x^2-2x+1)(x-2) \end{gathered}[/tex]Answer
The expression for the area is
[tex]A=(3x^2-2x+1)(x-2)[/tex]
