Find the Remainder (25x^5-5x^4+14x^3+8x^2+4)/(5x^2+2x-1)

$\frac{25 x^{5} - 5 x^{4} + 14 x^{3} + 8 x^{2} + 4}{5 x^{2} + 2 x - 1}$

To calculate the remainder, first divide the polynomials.

Set up the polynomials to be divided. If there is not a term for every exponent, insert one with a value of $0$ .

The final answer is the quotient plus the remainder over the divisor.

$5 x^{3} - 3 x^{2} + 5 x - 1 + \frac{7 x + 3}{5 x^{2} + 2 x - 1}$

Since the last term in the resulting expression is a fraction, the numerator of the fraction is the remainder.

$7 x + 3$
