How do you use polynomial synthetic division to divide (18x^2-15x-25)div(x-5/3) and write the polynomial in the form p(x)=d(x)q(x)+r(x)?

The answer is =(x-5/3)(18x+15)+0

Explanation:

Perform the synthetic division

color(white)(aaaa)5/3color(white)(aaaa)|18color(white)(aaaa)-15color(white)(aaaa)-25

color(white)(aaaa)color(white)(aaaaaa)|color(white)(aaaaaaaa)30color(white)(aaaaaa)25

color(white)(aaaa)color(white)(aaaaaa)|18color(white)(aaaaaa)15color(white)(aaaaaaa)0

Therefore,

18x^2-15x-25=(x-5/3)(18x+15)+0

The quotient is =18x+15 and the remainder is =0
