Step 1.1.1

Multiply $4$ by $1$ .

$- 2 P + 4 + 1.5 \cdot (- 2) = 0$

Step 1.1.2

Multiply $1.5$ by $- 2$ .

$- 2 P + 4 - 3 = 0$

$- 2 P + 4 - 3 = 0$

Step 1.2

Subtract $3$ from $4$ .

$- 2 P + 1 = 0$

$- 2 P + 1 = 0$

Step 2

Subtract $1$ from both sides of the equation.

Step 3.3.1.2.1

Rewrite $- 2$ as $- 1 (2)$ .

$P = \frac{- 1 \cdot 1}{- 1 \cdot 2}$

Step 3.3.1.2.2

Cancel the common factor.

$P = \frac{- 1 \cdot 1}{- 1 \cdot 2}$

Step 3.3.1.2.3

Rewrite the expression.

$P = \frac{1}{2}$

$P = \frac{1}{2}$

$P = \frac{1}{2}$

$P = \frac{1}{2}$

$P = \frac{1}{2}$

Step 4

The result can be shown in multiple forms.

Exact Form:

$P = \frac{1}{2}$

Decimal Form:

$P = 0.5$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
