Question

the last long one... subtract. (0.03x^3-0.04x^2+0.02x) - (0.02x^3+0.07x^2-5) who can help me ???

Answer 1

(0.03x^3-0.04x^2+0.02x) - (0.02x^3+0.07x^2-5)


0.03x^3-0.04x^2+0.02x - 0.02x^3-0.07x^2+5


Now combine like terms

Answer 2

So for example, 0.03x^3 and - 0.02x^3 are like terms, which means...


0.03x^3 - 0.02x^3


(0.03 - 0.02)x^3


0.01x^3

--------------------

So

0.03x^3 - 0.02x^3

becomes

0.01x^3

Answer 3

Do the same with the rest of the terms
