Solve $x^2+4x-5=0$

Step-by-step solution

1. Step 1 · Standard form
   $$x^2+4x-5=0$$

   Identify a = 1, b = 4, c = −5.

2. Step 2 · Factoring
   $$(x+5)(x-1)=0$$

   Factors of −5 that add to 4 are +5 and −1.

3. Step 3 · Zero product property
   $$x=-5,x=1$$

   Set each factor to zero and solve.
