3.1 Pull out like factors :
Equation at the end of step 3 : -5 • (x + 5) = 0 Step 4 :Equations which are never true :-5x - 25 = -5 • (x + 5)
4.1 Solve : -5 = 0
Solving a Single Variable Equation :This equation has no solution.
A a non-zero constant never equals zero.
4.2 Solve : x+5 = 0
One solution was found : x = -5Subtract 5 from both sides of the equation :
x = -5
