1. Problem Description

The problem asks us to find the roots of the quadratic equation 12x25=17x12x^2 - 5 = 17x. We need to express the answer as an integer or a fraction, separating multiple roots by commas.

2. Solution Steps

First, we rewrite the equation in standard quadratic form: ax2+bx+c=0ax^2 + bx + c = 0.
12x217x5=012x^2 - 17x - 5 = 0
We can solve this quadratic equation by factoring. We look for two numbers that multiply to 12×5=6012 \times -5 = -60 and add up to 17-17. These numbers are 20-20 and 33. We rewrite the middle term using these two numbers:
12x220x+3x5=012x^2 - 20x + 3x - 5 = 0
Now we factor by grouping:
4x(3x5)+1(3x5)=04x(3x - 5) + 1(3x - 5) = 0
(4x+1)(3x5)=0(4x + 1)(3x - 5) = 0
Setting each factor to zero gives us the two possible values for xx:
4x+1=04x=1x=144x + 1 = 0 \Rightarrow 4x = -1 \Rightarrow x = -\frac{1}{4}
3x5=03x=5x=533x - 5 = 0 \Rightarrow 3x = 5 \Rightarrow x = \frac{5}{3}
Therefore, the roots are 14-\frac{1}{4} and 53\frac{5}{3}.

3. Final Answer

14,53-\frac{1}{4}, \frac{5}{3}
