Need ASAP. Solve with square root method.

x = 1 ± 3

Step-by-step explanation:

Given

(x - 1)² - 18 = 0 ( add 18 to both sides )

(x - 1)² = 18 ( take the square root of both sides )

x - 1 = ± = ± = ± 3 ( add 1 to both sides )

x = 1 ± 3, thus the exact solutions are

x = 1 - 3

x = 1 + 3

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
