1. Problem Description

The problem is to find all the roots of the quadratic equation 5x2=6x15x^2 = 6x - 1.

2. Solution Steps

First, we need to rewrite the equation in the standard quadratic form ax2+bx+c=0ax^2 + bx + c = 0.
5x2=6x15x^2 = 6x - 1
5x26x+1=05x^2 - 6x + 1 = 0
Now, we can use the quadratic formula to find the roots of the equation. The quadratic formula is:
x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
In our case, a=5a = 5, b=6b = -6, and c=1c = 1. Plugging these values into the quadratic formula:
x=(6)±(6)24(5)(1)2(5)x = \frac{-(-6) \pm \sqrt{(-6)^2 - 4(5)(1)}}{2(5)}
x=6±362010x = \frac{6 \pm \sqrt{36 - 20}}{10}
x=6±1610x = \frac{6 \pm \sqrt{16}}{10}
x=6±410x = \frac{6 \pm 4}{10}
Now we have two possible solutions:
x1=6+410=1010=1x_1 = \frac{6 + 4}{10} = \frac{10}{10} = 1
x2=6410=210=15x_2 = \frac{6 - 4}{10} = \frac{2}{10} = \frac{1}{5}

3. Final Answer

The roots are 1,151, \frac{1}{5}.
