Question

(x+3)^3 +3(x+3)^2 -2(x+3)

Answer 1

Answer:

$(x+3)^2 + 3(x+3)^2 - 2(x+3)$

$(x^2 + 6x + 9 ) + 3(x^2 + 6x + 9) - 2x- 6$

$x^2 + 6x + 9 + 3x^2 + 18x + 27 - 2x- 6$

$4x^2 +22x + 30$

Answer 2

Answer:x³+12x²+43x+48

Step by step explanation:

=X³+9x²+27x+27+3x²+18x+27+(-2)(x)+(-2)(3)

=x³+9x²+27x+27+3x²+18x+27+-2x+-6

=(x³)+(9x²+3x²)+(27x+18x+-2x)+(27+27+-6)

x³+12x²+43x+48
