Answer:

b=-2aH

Step-by-step explanation:

H=-b/2a

Apply cross multiplication

H×2a=-b

2aH=-b

In the question you are to find positive b not negative b so you have to take negative b to the left hand side of the equation to become positive b and take 2aH to the right hand side to become -2aH

therefore b=-2aH

<h3>Answer ↓</h3>

option B.

Calculations ↓

First, let's think of two numbers so that :

if we multiply these numbers, we'll get 4
if we add these numbers, we'll get 5

These numbers are :

4 and 1

Plug these numbers here :

(x+4) (x+1)

So the correct factored form of this expression is

Option B) (x+4)(x+1)
