Top-left (x-7.5)^2=43.25

Step-by-step explanation:

Complete the square

x^2-15x+15=2

x^2-15x+13=0

(x-7.5)^2-(7.5)^2+13=0

(x-7.5)^2-56.25+13=0

(x-7.5)^2-43.25=0

(x-7.5)^2=43.25

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
