$x^{2} = 7 x$

Step 1

Subtract $7 x$ from both sides of the equation.

$x^{2} - 7 x = 0$

Step 2

Factor $x$ out of $x^{2} - 7 x$ .

Step 2.1

Factor $x$ out of $x^{2}$ .

$x \cdot x - 7 x = 0$

Step 2.2

Factor $x$ out of $- 7 x$ .

$x \cdot x + x \cdot - 7 = 0$

Step 2.3

Factor $x$ out of $x \cdot x + x \cdot - 7$ .

$x (x - 7) = 0$

$x (x - 7) = 0$
