Answer:
The missing number in Sari's factorization is 3.
Step-by-step explanation:
The given polynomial is,
\(=2x^2 + 5x + 3\)
From quadratic equations, applying middle term factorization,
\(=2x^2 + 2x+3x + 3\)
\(=2x(x + 1)+3(x + 1)\)
\(=(2x+3)(x + 1)\)
Comparing this to the given expression, the missing number in Sari's factorization is 3.
