Finding the roots of a Quadratic Equation by Completing the Square
1.) x^2+10x+25=0
What's the answer.??



Sagot :

Actually, x^2+10x+25 is a perfect square which is equal to (x+5)^2. So no need to perfect the square. Square the both sides so it becomes x+5=0. Transpose by APE so bit becomes x=-5...
