The positive solution to the equation x^2- 4 = 6

VARVARA [1.3K]

Answer:

In the form of $a+\sqrt{b}$ ,

a = 3
b = 13

Explanation:

The equation can be rewritten as:

$x^{2} -6x-4=0$

Find the solutions using the quadratic formula:

a = 1
b = -6
c = -4

$x=\frac{-b+-\sqrt{b^{2}-4ac} }{2a} \\\\=\frac{-(-6)+-\sqrt{(-6)^{2} -4(1)(-4)} }{2(1)} \\\\=\frac{6+-\sqrt{36+16} }{2} \\\\=\frac{6+-\sqrt{52} }{2} \\\\=\frac{2(3)+-2\sqrt{13} }{2} \\\\=\left \{ {{x_{1}=3+\sqrt{13} } \atop {x_{2}=3-\sqrt{13} }} \right.$
