Simplify and combine like terms.

Simplify each term.

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

Move $x$ .

$4 x^{2} - 32 x < 4 (x \cdot x) + 4 x \cdot - 9 - 2 x - 2 \cdot - 9$

Multiply $x$ by $x$ .

$4 x^{2} - 32 x < 4 x^{2} + 4 x \cdot - 9 - 2 x - 2 \cdot - 9$

Multiply $- 9$ by $4$ .

$4 x^{2} - 32 x < 4 x^{2} - 36 x - 2 x - 2 \cdot - 9$

Multiply $- 2$ by $- 9$ .

$4 x^{2} - 32 x < 4 x^{2} - 36 x - 2 x + 18$

Subtract $2 x$ from $- 36 x$ .

$4 x^{2} - 32 x < 4 x^{2} - 38 x + 18$

Move all terms containing $x$ to the left side of the inequality.

Subtract $4 x^{2}$ from both sides of the inequality.

$4 x^{2} - 32 x - 4 x^{2} < - 38 x + 18$

Add $38 x$ to both sides of the inequality.

$4 x^{2} - 32 x - 4 x^{2} + 38 x < 18$

Combine the opposite terms in $4 x^{2} - 32 x - 4 x^{2} + 38 x$ .

Subtract $4 x^{2}$ from $4 x^{2}$ .

$- 32 x + 0 + 38 x < 18$

Add $- 32 x$ and $0$ .

$- 32 x + 38 x < 18$

Add $- 32 x$ and $38 x$ .

$6 x < 18$

Divide each term in $6 x < 18$ by $6$ and simplify.

Divide each term in $6 x < 18$ by $6$ .

$\frac{6 x}{6} < \frac{18}{6}$

Simplify the left side.

Cancel the common factor of $6$ .

Cancel the common factor.

$\frac{6 x}{6} < \frac{18}{6}$

Divide $x$ by $1$ .

$x < \frac{18}{6}$

Simplify the right side.

Divide $18$ by $6$ .

$x < 3$

Step 2
