Q. Extraneous solutions of equationsRania solves the equation below by first squaring both sides of the equation.−5=3x−7What extraneous solution does Rania obtain?x=□
Square Both Sides: Step 1: Square both sides of the equation to eliminate the square root.−5=3x−7(−5)2=(3x−7)225=3x−7
Solve for x: Step 2: Solve for x.25=3x−725+7=3x32=3xx=332
Check for Extraneous Solutions: Step 3: Check for extraneous solutions by substituting x back into the original equation.x=332−5=3(332)−7−5=32−7−5=25−5=5
