Answer:

9x(9x+3) +3(9x+3) (9x+3)

9x(9x+3) +3(9x+3) (9x+3)= (81x²+27x+27x+9) (9x+3)

9x(9x+3) +3(9x+3) (9x+3)= (81x²+27x+27x+9) (9x+3)= (81x²+54x+9) (9x+3)

9x(9x+3) +3(9x+3) (9x+3)= (81x²+27x+27x+9) (9x+3)= (81x²+54x+9) (9x+3)= 81x²(9x+3) +54x(9x+3) +9(9x+3)

= 729x³+243+486x²+162+81x+27

= 729x³+486x²+81x+243+162+27

= 729x³+486x²+81x+432
