Question

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

Answer 1

b=11

Step-by-step explanation

The given quadratic equation is

`(2x - 1)(x + 6) = 0`

We expand to get:

`2 {x}^(2) + 12x - x - 6 = 0`

We simplify further by combining the x terms.

`2 {x}^(2) + 11x - 6 = 0`

This is the standard form.

Comparing to

`a{x}^(2) + bx + c= 0`

We have b=11
