Answer 2

I can help you solve this equation. First, let's simplify the equation by moving all the terms to one side and combining the like terms. We get:

$$4x^2 + 13x - 5/14 = 0$$

Next, we can use the quadratic formula to find the values of x that satisfy the equation. The quadratic formula is:

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

where a, b, and c are the coefficients of the quadratic equation. In our case, we have:

$$a = 4, b = 13, c = -5/14$$

Plugging these values into the quadratic formula, we get:

$$x = \frac{-13 \pm \sqrt{13^2 - 4(4)(-5/14)}}{2(4)}$$

Simplifying further, we get:

$$x = \frac{-13 \pm \sqrt{289/7}}{8}$$

To get the exact values of x, we need to rationalize the denominator of the square root. We can do this by multiplying and dividing by $\sqrt{7}$:

$$x = \frac{-13 \pm \sqrt{289/7} \cdot \sqrt{7}}{8}$$

$$x = \frac{-13 \pm \sqrt{2023}}{8}$$

These are the exact solutions of the equation. To get the approximate solutions, we can use a calculator to find the decimal values of the square roots. We get:

$$x \approx -0.25 \text{ or } -0.75$$

You can check your answers by plugging them back into the original equation and verifying that both sides are equal.
