Answer:
1. X^2+1/2x =

2. X^2+2x-3 =

3. (2x-3)^2 = (2x-3)(2x-3)
4. X^3+2x^2-19x-20 =

Explanation:
Each expression can be written as a product of linear factors as follows
1. X^2+1/2x ⇒

=

Hence, X^2+1/2x =

2. X^2+2x-3 ⇒




Hence, X^2+2x-3 =

3. (2x-3)^2 ⇒


Hence, (2x-3)^2 = (2x-3)(2x-3)
4. X^3+2x^2-19x-20 ⇒


First,

∴

Hence, X^3+2x^2-19x-20 =
