According to Vieta's Formulas, if
are solutions of a given quadratic equation:
Then: is the completely factored form of
.
If choose
, then:
So, according to Vieta's formula, we can get:
But
:
Anything multiplied by zero is zero
Answer:
Step-by-step explanation:
We want to find the equation of the line that goes through: !6,-10) and is perpendicular to the line
Let's simplify the equation of the line to get:
The slope of this line is -5.
The perpendicular to this line has a slope of
The equation going through (6,-10) is
We substitute to get;
Expand;
The number that should go in the box is 6.
