Shirley has a credit card that uses the previous balance method. The opening
balance of one of her 30-day billing cycles was $2830, but that was her
balance for only the first 2 days of the billing cycle because she then paid off
her entire balance and didn't make any new purchases. If her credit cards
APR is 19%, which of these expressions could be used to calculate the
amount Shirley was charged in interest for the billing cycle?

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).
