2x² - 4x = 14

<u>Divide by 2 through:</u>

x² - 2x = 7

<u>Add in the term (b/2)² :</u>

x² - 2x + (2/2)² = 7 + (2/2)²

<u>Complete the square:</u>

(x - 1)² = 7 + 1

<u>Combine like terms:</u>

(x - 1)² = 8

Answer: (x - 1)² = 8

------------------------------------------------------------------------------------------------------------

The question did not ask to solve x. But here is the solution if needed to solve x:

(x - 1)² = 8

x - 1 = ±√8

x = 1 ±√+8

x =1 + 2√2 or x = 1 - 2√2

Answer: x =1 + 2√2 or x = 1 - 2√2

denis-greek [22]

The situation forms the right triangle above:

Where x is the length of the ladder.

Apply the Pythagorean theorem:

c^2 = a^2 +b^1

where:

c = hypotenuse = longest side = x

A &b = the other 2 legs of the triangle

Replacing:

x^2 = 60^2 + 15^2

Solve for x

x^2 = 3,600 + 225

x^2 = 3,825

x =√3,825

x = 61.85 ft
