Question

Fórmula de Bhaskara: - x^2 - x + 6 = 0

Answer 1

-  X² - X  + 6 = 0  ( - 1 )

x² + x - 6 = 0

delta = ( 1)²  - [ 4 * 1 *( -6 ) ]   = 1  +  24  =  25  ou +-V25  = +-5 *** ****

x = ( -1 +-5 )/2

x1 = -6/2 =-3 *****

x2 = 4/2 = 2 *****

Answer 2

-x^2 -x +6 b^2-4ac = (-1)^2 -4(-6)                   1+24=25 (-b + ou - √25) (1 + 5) ÷ 2=3         ou (1-5) ÷ 2=-2  x^1=3, x^2= -2
