Write the quadratic equation in standard form and then choose the value of "b." (2x - 1)(x + 6) = 0 -4 11 12

2x^2 + 11x - 6

b = 11

Step-by-step explanation:

To write the equation in standard form, use the distributive property to multiply. Then combine like terms.

(2x - 1)(x + 6)

2x^2 - x + 12x - 6

2x^2 + 11x - 6

Now written in the standard form of a quadratic ax^2 + bx + c, the value of b here is 11.
