(If you would not realise of that, you can always use the formula to solve second-degree equations: #x=(-b+-sqrt(b^2-4ac))/(2a)#, and in this case you would obtain the single solution x=(-1), which you must again change to x+1 when you. 3 Solve : x+1 = 0 Subtract 1 from both sides of the equation : x = -1. gray kitchen trash can x=\frac{-\left(-2\right)±\sqrt{\left(-2\right)^{2}-4\times 1\left(-15\right)}}{2} All equations of the form ax^{2}+bx+c=0 can be solved using the quadratic formula: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. To find a and b, set up a system to be solved Since ab is positive, a and b have the same sign.
