Question

If a rectangular poster has an area of

(2x 2 − 9x + 10) square units, which of the
following could describe the dimensions of the
poster?
A (2x − 2) units by (x − 5) units
B (2x − 10) units by (x + 1) units
C (2x − 5) units by (x − 2) units
D (2x − 1) units by (x − 10) units

Answer 1

`2x ^2 - 9x + 10=\\ 2x^2-4x-5x+10=\\ 2x(x-2)-5(x-2)=\\ (2x-5)(x-2) \Rightarrow C`
