solvefor I,V= P/I+20I

解

解く

I, V = \frac{P}{I} + 20 I

I = \frac{V + V ^{2} - 80 P}{40}, I = \frac{V - V ^{2} - 80 P}{40}

解答ステップ

V = \frac{P}{I} + 20 I

以下で両辺を乗じる:

I

V I = P + 20 I^{2}

解く

V I = P + 20 I^{2} : I = \frac{V + V ^{2} - 80 P}{40}, I = \frac{V - V ^{2} - 80 P}{40}

I = \frac{V + V ^{2} - 80 P}{40}, I = \frac{V - V ^{2} - 80 P}{40}
