Q. Solve for x. Enter the solutions from least to greatest.(x−7)2−25=0 lesser x=_____ greater x=_____
Recognize Difference of Squares: Simplify the equation (x−7)2−25=0 by recognizing that it is a difference of squares.(x−7)2−25 can be factored into ((x−7)+5)((x−7)−5).So, (x−7)2−25=((x−7)+5)((x−7)−5)=0.
Set Factors Equal to Zero: Set each factor equal to zero to find the values of x.First factor: (x−7)+5=0 which simplifies to x−2=0.Second factor: (x−7)−5=0 which simplifies to x−12=0.
Solve for x: Solve each equation for x.For the first factor: x−2=0 gives x=2.For the second factor: x−12=0 gives x=12.
List Solutions: List the solutions from least to greatest.The lesser x is x=2.The greater x is x=12.
