Chris is checking to determine if the expressions 2 (x + 3) and 2 x + 4 + 2 x are equivalent. When x = 1, he correctly finds that both expressions have a value of 8. When x = 2, he correctly evaluates the first expression to find that 2 (x + 3) = 10. What is the value of the second expression when x = 2, and are the two expressions equivalent?

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
