Determine if Linear 4x(x-3)=y

$4 x (x - 3) = y$

Step 1

Solve the equation for $y$ .

Rewrite the equation as $y = 4 x (x - 3)$ .

$y = 4 x (x - 3)$

Simplify $4 x (x - 3)$ .

Apply the distributive property.

$y = 4 x \cdot x + 4 x \cdot - 3$

Multiply $x$ by $x$ by adding the exponents.

Move $x$ .

$y = 4 (x \cdot x) + 4 x \cdot - 3$

Multiply $x$ by $x$ .

$y = 4 x^{2} + 4 x \cdot - 3$

Multiply $- 3$ by $4$ .

$y = 4 x^{2} - 12 x$

Step 2

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be $0$ or $1$ for each of its variables. In this case, the degree of variable $y$ is $1$ and the degree of variable $x$ is $2$ .
