(2x - 1)(x - 2)

(2x + 1)(x - 2)

(2x - 2)(x - 1)

(2x + 2)(x - 1)

(2x+2)(2x+6)

(2x-4)(2x+3)

(4x+1)(x+3)

(2x+1)(2x+3)

$$5x^2+9x+3x+4$$  and then continue factoring by grouping

$$5x^2-10x\ -2x+4$$  and then continue factoring by grouping. 

$$5x^2+10x+2x+4$$  and then continue factoring by grouping. 

$$5x^2+4x+5x+4$$  and then continue factoring by grouping. 

Factoring by difference of squares, factoring by trial and error, and factoring by using the AC method.

Factoring by grouping, factoring using the quadratic formula, and factoring by completing the square.
