Answer:
2x² + 9x - 5
Here the value of b = 9.
Step-by-step explanation:
The standard form of a quadratic is [tex]ax^2 + bx + c[/tex]. 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.
