solvefor x,z^2=x^2+7.5y^2

解

解く

x, z^{2} = x^{2} + 7.5 y^{2}

解

x = z^{2} - 7.5 y^{2}, x = - z^{2} - 7.5 y^{2}

解答ステップ

z^{2} = x^{2} + 7.5 y^{2}

辺を交換する

x^{2} + 7.5 y^{2} = z^{2}

7.5 y^{2}

を右側に移動します

x^{2} = z^{2} - 7.5 y^{2}

x^{2} = f (a)

の場合, 解は

x = f (a), - f (a)

x = z^{2} - 7.5 y^{2}, x = - z^{2} - 7.5 y^{2}

2^2+sqrt(-1)+x^2=2

2^{2} + - 1 + x^{2} = 2

125 x^{2} + 20 = 0

solvefor x,9x^2+16y^2=0

so l v e f or x, 9 x^{2} + 16 y^{2} = 0

l(q)=5q^2-8q+12

l (q) = 5 q^{2} - 8 q + 12

solvefor t,dt+0.5t=dt(0.5t)

so l v e f or t, d t + 0.5 t = d t (0.5 t)
