Math Problem Statement

Use factorising to solve the equation: x^2 - 2x = 0

Solution

The problem presented is to solve the quadratic equation x22x=0x^2 - 2x = 0 by factoring.

Solution:

  1. Factorize the equation: The equation is x22x=0x^2 - 2x = 0. To factorize: x(x2)=0x(x - 2) = 0

  2. Solve for xx: Using the zero product property, set each factor equal to 0: x=0orx2=0x = 0 \quad \text{or} \quad x - 2 = 0 Solve the second equation: x=2x = 2

  3. Solutions: The solutions to the equation are: x=0andx=2x = 0 \quad \text{and} \quad x = 2
