<em>Quadratic equation, vertex shape, parabola
</em>
For this case we have to rewrite the given quadratic equation, in the form of vertex, for this, we must take into account that a quadratic equation of the form 
, can be rewritten in the form of vertex as: 
Vertice is the lowest or highest point of the parabola. The vertex is given by: 
. So, let: 
, to find the equation in the form of vertex, we follow the steps below:
Step 1:
We take the common factor to the first two terms of the equation:
Step 2:
We work square:
We divide the coefficient of the term 
by 2 and its result is squared, that is:
So, we have:
Step 3:
We simplify:
Step 4:
We factor:
Thus, 
Answer:
The equation in the form of vertex is: , and the vertex is 
Answer:
15 years old
Step-by-step explanation:
The equation would be
8x + 2x + x = 53
3x = 45
x = 15
Hello,
When you are dilating a shape you are simply making the sides larger or smaller. However, the angles will remain the same.
Imagine a stop sign being made twice as large. The side would be twice a long, however all of the angles will remain the same.
Good luck,
