Question

Add the following polynomial 3x^3-5x2 + 8x^3+2x^2-7x​

Answer 1

Answer:

$3x^3-5x^2+8x^3+2x^2-7x=11x^3-3x^2-7x$

Step-by-step explanation:

$3x^3-5x^2+8x^3+2x^2-7x$

$\mathrm{Group\:like\:terms}$

$=3x^3+8x^3-5x^2+2x^2-7x$

$\mathrm{Add\:similar\:elements:}\:-5x^2+2x^2=-3x^2$

$=3x^3+8x^3-3x^2-7x$

$\mathrm{Add\:similar\:elements:}\:3x^3+8x^3=11x^3$

$=11x^3-3x^2-7x$
