Answer

$1.30x^4+0.35x^3+9.53x^2+2x+0.96$

Work Step by Step

Add the polynomials by adding the similar terms (which are found in columns) to obtain: $=(0.05x^4+1.5x^4+(-0.25x^4))+(0.12x^3+(-0.02x^3)+0.25x^3)+(-0.5x^2+0.02x^2+0.01x^2+10x^2)+2x+(0.15+0.85+(-0.04)) \\=1.30x^4+0.35x^3+9.53x^2+2x+0.96$
