c-2*sqrt(c)-0.59=0

解答

c - 2 \cdot c - 0.59 = 0

解答

c = \frac{5.18 + 25.44}{2}

+1

十进制

c = 5.11190 \dots

求解步骤

c - 2 c - 0.59 = 0

去除平方根

4 c = c^{2} - 1.18 c + 0.3481

解

4 c = c^{2} - 1.18 c + 0.3481 : c = \frac{5.18 + 25.44}{2}, c = \frac{5.18 - 25.44}{2}

c = \frac{5.18 + 25.44}{2}, c = \frac{5.18 - 25.44}{2}

验证解:

c = \frac{5.18 + 25.44}{2}

真

, c = \frac{5.18 - 25.44}{2}

假

解是

c = \frac{5.18 + 25.44}{2}

x - 4 x + 1 = 0

sqrt(1+x\sqrt{x^2+4)}=x+1

1 + x x^{2} + 4 = x + 1

sqrt(25+5x)+sqrt(3x+31)=4

25 + 5 x + 3 x + 31 = 4

sqrt(x+c^2)+a=2b

x + c^{2} + a = 2 b

\frac{4}{3 x ^{\frac{4}{3}}} = 0
