Ronnie Schechter · Accepted Answer

Step 1  Consider the polynomials,  −2(4x7+3x9+2x8)+(−9x9−8x7+3+5x9)  Open the parenthesis,  −2+4x7+3x9+2x8−9x9−8x7+3+5x9  Step 2  Group like terms,  (3x9−9x9+5x9+2x8+4x7−8x7−2+3)  Step 3  Add the similar elements,  (3x9−9x9+5x9+2x8+4x7−8x7−2+3)  (3x9−9x9+5x9)+2x8+(4x7−8x7)+(−2+3)  −x9+2x8−4x7+1  Hence the addition of polynomial,  (−2+4x7+3x9+2x8)+(−9x9−8x7+3+5x9)=(−x9+2x8−4x7+1).

Add the polynomial −2(4x7+3x9+2x8)+(−9x9−8x7+3+5x9)
