We want to write the given function in the form ax^2 + bx + c = 0.

We foil the left side.

(2x - 1)(x + 5) =0

2x^2 + 10x - x - 5 = 0

2x^2 + 9x - 5 = 0

Can you see the value of "b"?

The b-value is the coefficient of x.

So, b = 9.

Done!

Can you explain it please and which method is correct?​
Ksju [112]

Answer:

The second one (answer of 3), but the other ones could've worked, they were just calculated wrong.

Step-by-step explanation:

Here's why each one did or didn't work:

First answer- you had the right idea by cancelling out the two in the denominator, however if you're going to divide 2, you have to divide it from everything in the equation. Meaning you would divide 4 by 2 to get 2, and then add the 1 + 2 to get final answer 3.

Second answer- since you added the numerator separately and then did the basic division, this worked.

Third one- similarly to the first one, you would have to also divide the 2 by 2 to get 1, then adding 1 + 2 to get 3.
