Answer:
x ≈ - 9.41, x ≈ - 6.59
Step-by-step explanation:
Given
x² + 16x + 62 = 0 ( subtract 62 from both sides )
x² + 16x = - 62
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(8)x + 64 = - 62 + 64
(x + 8)² = 2 ( take the square root of both sides )
x + 8 = ± ( subtract 8 from both sides )
x = - 8 ±
Hence
x = - 8 - ≈ - 9.41
x = - 8 + ≈ - 6.59
Answer:
Step-by-step explanation:
It is important to remember that the formula for calculate the area of a square is:
Where "s" is the side lenght of the square.
From the figure you can identify that the side lenght of the square can be represented with this expression:
Therefore, the following expression represents the area of the square:
In order to simplify it, you need to remember that:
Then, you get that the polynomial that represents the area of the given square, is:
