q(x)=2,x^2+6r(x)=-2

解

q (x) = 2, x^{2} + 6 r (x) = - 2

(r \in R, r \in R, x = - 3 r + 9 r^{2} - 2, x = - 3 r - 9 r^{2} - 2, q = 2 q = 2)

解答ステップ

[q = 2 x^{2} + 6 r (x) = - 2]

以下のために

x^{2} + 6 r (x) = - 2

を解く:

q = 2 : (r \in R, x = - 3 r + 9 r^{2} - 2, q = 2), (r \in R, x = - 3 r - 9 r^{2} - 2, q = 2)

元のequationに当てはめて解を検算する

ゆえに,

q = 2, x^{2} + 6 r (x) = - 2

の最終的な解は

(r \in R, r \in R, x = - 3 r + 9 r^{2} - 2, x = - 3 r - 9 r^{2} - 2, q = 2 q = 2)
