Question

x^2+2x-48=-0

Answer 1

same formula : if your equation is ax^2 + bx + c = 0
delta = b^2 - 4xaxc
x1 = (-b -sqrt(delta))/2a
x2 = (-b +sqrt(delta))/2a

Answer 2

here delta is negative so you don't have any solution..

Answer 3

hmmm .... im wondering if there is a number "-0" ;)

Answer 4

just slightly to the left of +0
