x^2=7^2+3^2

Lösung

x^{2} = 7^{2} + 3^{2}

x = 58, x = - 58

Dezimale

x = 7.61577 \dots, x = - 7.61577 \dots

Schritte zur Lösung

x^{2} = 7^{2} + 3^{2}

Vereinfache

7^{2} + 3^{2} : 58

Für

x^{2} = f (a)

sind die Lösungen

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

x = 58, x = - 58

so l v e f or x, x^{2} - 10 x y + y^{2} = 10

(3 x + 1)^{2} = (5 x + 5) (x + 2)

x^{2} + 8 x = a + b x^{2} + c (x + 1) (x + 3)

x^{2} - 9 = 25

x^{2} - 9 = 27
