Question

Find the sum. (adding and subtracting polynomials)

Find the sum. (-8x - 12) + (9x + 4)=
Find the sum. (-3p^3 + 5p^2 - 2p) + (3r^2 - 3r)
Find the sum. ( -3p^3 + 5p^2 - 2p) + (-p^3 - 8p^2 - 15p)
Find the sum. ( 9r^2+4r-7) + (3r^2-3r)

Answer 1

(-8x - 12) + (9x + 4)= x-8

(-3p^3 + 5p^2 - 2p) + (3r^2 - 3r)= -3p^3+5p^2-2p+3r^2-3r

( -3p^3 + 5p^2 - 2p) + (-p^3 - 8p^2 -15p)= -4p^3-3p^2-17p

. ( 9r^2+4r-7) + (3r^2-3r)= 12r^2+r-7
