<em><u>Hello, there! :)</u></em>
<u><em>Answer:</em></u>
<u><em>x=-5 </em></u>
<u><em>B. -5</em></u>
<u><em>*The answer must have a negative sign.*</em></u>
Step-by-step explanation:
Definition of subtraction property of equality.
Subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
First, you had to switch sides.
Then, you subtract by 12 from both sides of an equation.
And finally, simplify or solve.
Hope this helps!
Thanks!

1 solution as the highest power on the unkown, x, is 1 so it’s a linear equation this causes it to have only 1 solution
Answer:
If 
then 
.
If 
then 
.
Step-by-step explanation:
In order to write the polynomial as the product of linear factors, we need to find the roots of the polynomial. A quadratic equation is defined as:
Because the given polynomial expression is a quadratic equation, we can use the following equations for calculating the roots:
Since the second term sign is not given, then we can write the expression as:
, in which a=1, b=s2 where 's' represents a sign (- or +), and c=10.
Using the equation for finding the roots we obtain:
; notice that 
; notice that (s2)²=2^2
If we consider 's' as possitive (+) the roots are:
and 
Whereas if we consider 's' as negative (-) the roots are:
and 
The above means that if the equation is , then we can express the polynomial as: .
But, if the equation is , then we can express the polynomial as: .
