Answer:

2x² + 9x - 5

Here the value of b = 9.

Explanation:

The standard form of a quadratic is
ax^2 + bx + c. To write the expression (2x - 1)(x + 5) in standard form, multiply the factors using the distributive property and combining like terms.

(2x - 1)(x + 5)

2x²- x + 10x - 5

2x² + 9x - 5

Here the value of b = 9.
