What number should be added to both sides of the equation to complete the square? x^2-10x=12​

Step-by-step explanation:

x²-10x = 12

Coefficient of the x term: -10

Divide in half: -5

Square it: (-5)² = 5²

Add 5² to both sides:

x²-10x+5² = 12+5²

(x-5)² = 37

the answer is 0.071

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
