Question

Simplify. (6x^3+x^5+2x^2−7−4x)−(3x^2−5x+2+5x^5+3x^4)

Answer 1

$(6 {x}^{3} + {x}^{5} + 2 {x}^{2} - 7 - 4x) - (3 {x}^{2} - 5x + 2 + 5 {x}^{5} + 3 {x}^{4} \\ ={x}^{5} + 6 {x}^{3} + 2 {x}^{2} - 4x - 7 -5 {x}^{5} - 3 {x}^{4} - 3 {x}^{2} + 5x - 2 \\ = - 4 {x}^{5} - 3 {x}^{4} + 6 {x}^{3} - {x}^{2} + x - 9$

Answer 2

The correct answer is -4x^5 - 3x^4 + 6x^3 - x^2 + x - 9.
