Question

encontre a raiz da equacao 6x² - 11x+3=0

Answer 1

6x² - 11x + 3 = 0 
► 
► FORMULA DE BASKHARA: 
► 
► ax² + bx + c = 0 
► 
► a = 6 
► b = -11 
► c = 3 
► 
► ∆² = b² - 4ac = (-11)² - 4*6*3 = 121 - 72 = 49 
► ∆ = √49 = 7 
► 
► x' = -b/2a + ∆/2a = 11/12 + 7/12 = 18/12 = 3/2 
► x" = -b/2a - ∆/2a = 11/12 - 7/12 = 4/12 = 2/6
