Two students, Jennifer and Jamal, factored the trinomial 4x2 − 6x − 4. Jennifer factored it as 2(x − 2)(2x + 1) and Jamal factored it as (x − 2)(4x + 2). Indicate which student factored the trinomial completely and which student did not, and explain why

Afarmer has a large field that is x feet in length. he wants to fence in a rectangular section in the middle of the field , leaving a length of 100 feet of open field behind each end of the fenced rectangle.he also wants the width of the fenced-in space to be 100 feet less than its length. find the expressions to represent the length and width of the fenced section of the field
