Question

The base of a triangle is represented by (2x − 6) and the height by (x − 2). Which polynomial expression BEST represents the area of the triangle?

Answer 1

x2 - 5x + 6 is the answer. Hope this helps.

Answer 2

Area of a triangle=
`(1)/(2) *base*height`
A=
`(1)/(2) *(2x-6)*(x-2)`
A=
`(1)/(2) ( 2x^(2) -4x-6x+12)`
A=
`x^(2) -2x-3x+6`
A=
`x^(2) -5x+6`
