The factorized expression is: [tex](x + 10)(x + 9)[/tex]

The quadratic expression is given as:

[tex]x^2 + 19x + 90[/tex]

Express 19x as 9x + 10x

[tex]x^2 + 9x + 10x + 90[/tex]

Factorize the expression

[tex]x(x + 9) + 10(x + 9)[/tex]

Factor out x + 9

[tex](x + 10)(x + 9)[/tex]

Hence, the factorized expression is: [tex](x + 10)(x + 9)[/tex]
