Answer:

[tex] {x}^{2} + 9x + 20[/tex]

Step-by-step explanation:

1) Use FOIL method: (a + b) (c + d) = ac + ad + bc + bd.

[tex] {x}^{2} + 5x + 4x + 20[/tex]

2) Collect like terms.

[tex] {x}^{2} + (5x + 4x) + 20[/tex]

3) Simplify.

[tex] {x}^{2} + 9x + 20[/tex]

Therefor, the answer is x² + 9x + 20.
