ANSWER

b=11

EXPLANATION

The given quadratic equation is

[tex](2x - 1)(x + 6) = 0[/tex]

We expand to get:

[tex]2 {x}^{2} + 12x - x - 6 = 0[/tex]

We simplify further by combining the x terms.

[tex]2 {x}^{2} + 11x - 6 = 0[/tex]

This is the standard form.

Comparing to

[tex]a{x}^{2} + bx + c= 0[/tex]

We have b=11
