solvefor x,f(a+4)=sqrt(8+4x)

Lösung

löse nach

x, f (a + 4) = 8 + 4 x

x = \frac{a ^{2} f ^{2} + 8 a f ^{2} + 16 f ^{2} - 8}{4}

Schritte zur Lösung

f (a + 4) = 8 + 4 x

Quadriere beide Seiten:

a^{2} f^{2} + 8 a f^{2} + 16 f^{2} = 8 + 4 x

a^{2} f^{2} + 8 a f^{2} + 16 f^{2} = 8 + 4 x

Löse

a^{2} f^{2} + 8 a f^{2} + 16 f^{2} = 8 + 4 x : x = \frac{a ^{2} f ^{2} + 8 a f ^{2} + 16 f ^{2} - 8}{4}

x = \frac{a ^{2} f ^{2} + 8 a f ^{2} + 16 f ^{2} - 8}{4}

x = 1 + x^{0.5}

3 x + 5 = 0

x^{2} + 9 = 1 - x

(x^{2} - 15)^{\frac{1}{2}} = 7

x + 1 = - 4
