Question

9x2-3x=5/36 -- METODO DE COMPLEMENTAR QUADRADO

Answer 1

Resposta:

9x²-3x=5/36

9x²-3x +(1/2)²-(1/2)²=5/36

(3x-1/2)²-(1/2)²=5/36

(3x-1/2)²= 5/36+1/4

(3x-1/2)² = 5/36+9/36

(3x-1/2)² = 14/36

(3x-1/2)² = 7/18

3x -1/2=±√(7/18)

3x= 1/2+√(7/18) ==>x' =1/6 +√(7/2)/9

3x= 1/2-√(7/18) ==>x''=1/6 -√(7/2)/9
