Identify the quadratic equation: Identify the quadratic equation to be solved.We are given the quadratic equation x2+10x+25=0. We need to find the values of x that satisfy this equation.
Factor the quadratic equation: Factor the quadratic equation.We need to find two numbers that multiply to 25 and add up to 10. The numbers 5 and 5 meet these criteria because 5×5=25 and 5+5=10.So, we can write the equation as (x+5)(x+5)=0.
Set each factor equal to zero: Set each factor equal to zero and solve for x.Since (x+5)(x+5)=0, we can set each factor equal to zero and solve for x.x+5=0Subtract 5 from both sides to solve for x.x=−5
Check for other possible solutions: Check for any other possible solutions.Since both factors are the same, (x+5), we only have one unique solution for x.x=−5
