Sari is factoring the polynomial 2x2 + 5x + 3. What is the missing number in her factorization?
sergejj [24]

Answer:

<em>The missing number in Sari's factorization is </em><em>3</em><em>.</em>

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.
