Question

Quizplus · Accepted Answer

Subtracting the second polynomial from the first gives: $8x^5 - 5x^5 + 9x^2 - 18x^2 - 2 - 10 = 3x^5 - 9x^2 - 12$.

Subtract the Polynomials (8x5+9x2−2)−(18x2+5x5+10)\left( 8 x ^ { 5 } + 9 x ^ { 2 } - 2 \right) - \left( 18 x ^ { 2 } + 5 x ^ { 5 } + 10 \right)(8x5+9x2−2)−(18x2+5x5+10)
