Answer:

The missing number in Sari's factorization is 3.

Step-by-step explanation:

The given polynomial is,

[tex]=2x^2 + 5x + 3[/tex]

From quadratic equations, applying middle term factorization,

[tex]=2x^2 + 2x+3x + 3[/tex]

[tex]=2x(x + 1)+3(x + 1)[/tex]

[tex]=(2x+3)(x + 1)[/tex]

Comparing this to the given expression, the missing number in Sari's factorization is 3.
