Math Problem Statement

3x^2-5x+1=0

Solution

The given equation is a quadratic equation in the form ax2+bx+c=0ax^2 + bx + c = 0, where:

  • a=3a = 3
  • b=5b = -5
  • c=1c = 1

To solve for xx, we can use the quadratic formula:

x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

Now, plug in the values of aa, bb, and cc:

x=(5)±(5)24(3)(1)2(3)x = \frac{-(-5) \pm \sqrt{(-5)^2 - 4(3)(1)}}{2(3)}

Simplifying step by step:

x=5±25126x = \frac{5 \pm \sqrt{25 - 12}}{6}

x=5±136x = \frac{5 \pm \sqrt{13}}{6}

So, the two possible solutions for xx are:

x=5+136orx=5136x = \frac{5 + \sqrt{13}}{6} \quad \text{or} \quad x = \frac{5 - \sqrt{13}}{6}

These are the exact solutions. If you'd like the decimal approximation:

x11.434andx20.233x_1 \approx 1.434 \quad \text{and} \quad x_2 \approx 0.233
