Solve for R P=i^2R

$P = i^{2} R$

Rewrite the equation as $i^{2} R = P$ .

$i^{2} R = P$

Divide each term in $i^{2} R = P$ by $i^{2}$ and simplify.

Divide each term in $i^{2} R = P$ by $i^{2}$ .

$\frac{i^{2} R}{i^{2}} = \frac{P}{i^{2}}$

Simplify the left side.

Cancel the common factor of $i^{2}$ .

Cancel the common factor.

$\frac{i^{2} R}{i^{2}} = \frac{P}{i^{2}}$

Divide $R$ by $1$ .

$R = \frac{P}{i^{2}}$

Simplify the right side.

Rewrite $i^{2}$ as $- 1$ .

$R = \frac{P}{- 1}$

Move the negative one from the denominator of $\frac{P}{- 1}$ .

$R = - 1 \cdot P$

Rewrite $- 1 \cdot P$ as $- P$ .

$R = - P$
