We have the following equation:
 2 (x-3) ^ 2 + 10 = 82
 We must clear x.
 We pass the constant terms to one side of the equation:
 2 (x-3) ^ 2 = 82 - 10
 2 (x-3) ^ 2 = 72
 (x-3) ^ 2 = 72/2
 (x-3) ^ 2 = 36
 Square root to both members:
 x-3 = +/- root (36)
 x-3 = +/- 6
 The solutions are:
 x1 = 6 + 3 = 9
 x2 = -6 + 3 = -3
 Answer:
 
x1 = 9
 
x2 = -3

A rectangle has the length that is five times longer than it’s width. If the perimeter of the rectangle is 12 inches, whats the
NemiM [27]
The width would be 1 inch.

Given: L = length = 5W; P = perimeter = 2(L+W) = 12 inches
Required: W = width; 
Formula: P=2(L+W) 
Solution:
              12 in = 2 (L + W)
              6 in = L + W
              6 in = 5W + W
              6 in = 6W
              1 in = W
Cross check:
              P = 2(L + W)
              12 in = 2(5 in + 1 in)
              12 in = 2(6 in)
              12 in = 12 in
