Step-by-step explanation:
Adding
Let's simplify step-by-step.
2x3−9x2+83x2−6x−57x3−10x+1+3+2x−5x2−4x3
=2x3+−9x2+83x2+−6x+−57x3+−10x+1+3+2x+−5x2+−4x3
Combine Like Terms:
=2x3+−9x2+83x2+−6x+−57x3+−10x+1+3+2x+−5x2+−4x3
=(2x3+−57x3+−4x3)+(−9x2+83x2+−5x2)+(−6x+−10x+2x)+(1+3)
=−59x3+69x2+−14x+4
Subtracting
Let's simplify step-by-step.
2x3−9x2+83x2−6x−57x3−10x+1−3+2x−5x2−4x3
=2x3+−9x2+83x2+−6x+−57x3+−10x+1+−3+2x+−5x2+−4x3
Combine Like Terms:
=2x3+−9x2+83x2+−6x+−57x3+−10x+1+−3+2x+−5x2+−4x3
=(2x3+−57x3+−4x3)+(−9x2+83x2+−5x2)+(−6x+−10x+2x)+(1+−3)
=−59x3+69x2+−14x+−2
Multiplying
Let's simplify step-by-step.
2x3−9x2+83x2−6x−57x3−10x+(1)(3)+2x−5x2−4x3
=2x3+−9x2+83x2+−6x+−57x3+−10x+3+2x+−5x2+−4x3
Combine Like Terms:
=2x3+−9x2+83x2+−6x+−57x3+−10x+3+2x+−5x2+−4x3
=(2x3+−57x3+−4x3)+(−9x2+83x2+−5x2)+(−6x+−10x+2x)+(3)
=−59x3+69x2+−14x+3
Dividing
Let's simplify step-by-step.
2x3−9x2+83x2−6x−57x3−10x+1/3+2x−5x2−4x3
=2x3+−9x2+83x2+−6x+−57x3+−10x+1/3+2x+−5x2+−4x3
Combine Like Terms:
=2x3+−9x2+83x2+−6x+−57x3+−10x+1/3+2x+−5x2+−4x3
=(2x3+−57x3+−4x3)(−9x2+83x2−5x2(−6x−10x+2x+(1/3)
=−59x3+69x2+−14x+1/3
