Identify Equation Type: Identify the type of equation and look for patterns.The equation x2−20x+100=0 is a quadratic equation in the form of ax2+bx+c=0.Notice that the equation can be factored because 100 is a perfect square and 20x is twice the product of the square root of 100 and x.
Factor Quadratic Equation: Factor the quadratic equation.x2−20x+100=(x−10)(x−10)=0This is because (x−10)2=x2−20x+100.
Solve for x: Solve for x by setting each factor equal to zero.Since (x−10)(x−10)=0, we have x−10=0.
Find x Value: Find the value of x.x−10=0 implies that x=10.
