Find the roots of the equation 12x−3+1x−5=1\frac{1}{2x-3} + \frac{1}{x-5} = 1 x≠32,5x \neq \frac{3}{2}, 5 (roots, equation, fractions, domain, quadratic)

Answer: The roots of the equation are x=8+322x = \frac{8 + 3\sqrt{2}}{2} and x=8−322x = \frac{8 - 3\sqrt{2}}{2}.

Step-by-step solution

Step 1: Combine fractions on the left side

To solve this equation, we first need to combine the fractions on the left-hand side. We do this by finding a common denominator, which is the product of the two denominators: (2x−3)(x−5)(2x-3)(x-5). Then, we cross-multiply the numerators with the opposite denominators and add them.

Step 2: Simplify the numerator and cross-multiply

Now, we simplify the numerator on the left side by combining like terms. Then, we multiply both sides of the equation by the denominator (2x−3)(x−5)(2x-3)(x-5) to eliminate the fraction, moving it to the right side.

Step 3: Expand the right side

We expand the product of the two binomials on the right side of the equation using the distributive property (FOIL method). This will result in a quadratic expression.

Step 4: Rearrange into standard quadratic form

To solve the quadratic equation, we need to rearrange it into the standard form ax2+bx+c=0ax^2 + bx + c = 0. We do this by moving all terms to one side of the equation and combining like terms.

Step 5: Apply the quadratic formula

Since the quadratic equation 2x2−16x+23=02x^2 - 16x + 23 = 0 cannot be easily factored, we use the quadratic formula to find the roots. Here, a=2a=2, b=−16b=-16, and c=23c=23.

Step 6: Substitute values and simplify

Substitute the values of aa, bb, and cc into the quadratic formula and simplify the expression. Remember to simplify the square root and then divide all terms by the common factor in the numerator and denominator.
