Simplifying
b2 + 12b + 35 = 0
Reorder the terms:
35 + 12b + b2 = 0
Solving
35 + 12b + b2 = 0
Solving for variable 'b'.
Factor a trinomial.
(7 + b)(5 + b) = 0
Subproblem 1
Set the factor '(7 + b)' equal to zero and attempt to solve:
Simplifying
7 + b = 0
Solving
7 + b = 0
Move all terms containing b to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + b = 0 + -7
Combine like terms: 7 + -7 = 0
0 + b = 0 + -7
b = 0 + -7
Combine like terms: 0 + -7 = -7
b = -7
Answer:
The answer in the attached figure
Step-by-step explanation:
we have

This is a linear equation
The slope is equal to 
The y-intercept is equal to the point
----> value of the function f(x) when the value of x is equal to zero
The x-intercept is equal to the point
----> value of x when the value of the function is equal to zero
using a graphing tool
see the attached figure
Yes, it is also a square number
A = w × l
A = (2x - 4) (x + 5)
