Final answer:
The correct answer is D. 2x² - (5/2)x - 3 = 0. The equation is multiplied by x to remove the fraction and then rearranged into the standard form of a quadratic equation.
Step-by-step explanation:
To rewrite the equation (3)/(x) = (5)/(2) + 2x as a quadratic equation in standard form, we need to first eliminate the fractions and then rearrange the terms. Multiplying every term by x to get rid of the fraction gives us 3 = (5/2)x + 2x^2. To combine like terms, let's multiply 2x^2 by 2/2 to have common denominators, yielding 3 = (5/2)x + (4/2)x^2. Now, rearranging and combining like terms to form ax² + bx + c = 0, we get 2x² - (5/2)x - 3 = 0, which is option D. Note that option A is incorrect because it suggests multiplying 5/2 by 2 in the term (5/2)x, which is unnecessary and incorrect; option B incorrectly converts the fractions; and option C is incorrect because it misrepresents the coefficients of x and x².
