Step-by-step explanation:
Solve the equation for x by finding a
, b
, and c of the quadratic then applying the quadratic formula.
Answer:
the length is 
and the width is 
Step-by-step explanation:
Let points A and B be placed on the x-axis. Their coordinates are 
and 
(because of parabola symmetry). Two other vertices lie on the parabola, then 
and 
The length of the side AB is 
and the length of the side AD is 
Thus, the area of the rectangle ABCD is
Find the derivative A':
Equate A' to 0:
The maximum area of the rectangle is
The dimensions of the rectangle are:
the length is 
and the width is 
The answer to this problem= 0
⇒6x + 2 + - 1 - 4x - 3 + - 2x + 2 = 0
⇒2 - 1 - 3 + 2 + 6x + -4x - 2x = 0
⇒1 - 3 + 2 + 6x + -4x - 2x = 0
⇒-2 + 2 + 6x + -4x + -2x = 0
⇒0 + 6x + -4x + -2x = 0
⇒6x - 4x - 2x = 0
⇒2x + -2x = 0
Combine like terms: 2x + -2x = 0
0 = 0
Solving
0 = 0
