$y = x (x - 3)$

Step 1

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

$y = a x^{2} + b x + c$

Step 2

Apply the distributive property.

$y = x \cdot x + x \cdot - 3$

Step 3

Simplify the expression.

Step 3.1

Multiply $x$ by $x$ .

$y = x^{2} + x \cdot - 3$

Step 3.2

Move $- 3$ to the left of $x$ .

$y = x^{2} - 3 x$
