8x^4+4x^3-39x^2+31x-148x4+4x3−39x2+31x−14

Explanation:

=8x^4-6x^3+4x^2+10x^3-15x^2+10x-28x^2+21x-14=8x4−6x3+4x2+10x3−15x2+10x−28x2+21x−14

Rearranging like terms together,
P=8x^4-6x^3+10x^3+4x^2-15x^2-28x^2+10x+21x-14=8x4−6x3+10x3+4x2−15x2−28x2+10x+21x−14

Further simplifying,
=8x^4+4x^3-39x^2+31x-14=8x4+4x3−39x2+31x−14
