x 2 − 4 x = 0 x ( x − 4 ) = 0 x = 0 ∨ x = 4
3 x 2 = 48 x 2 = 16 x = − 4 ∨ x = 4 or 3 x 2 − 48 = 0 3 ( x 2 − 16 ) = 0 3 ( x − 4 ) ( x + 4 ) = 0 x = 4 ∨ x = − 4
To solve the equation x 2 − 4 x = 0 , factor it into x ( x − 4 ) = 0 . Then, set each factor to zero to find the solutions: x = 0 and x = 4 . This process utilizes the zero product property to determine the roots of the equation.
