Question

the equation 3x^4-2x+9x^2+3-7x+x^3-2x^2=3x^4+x^3+7x^2-9x+3 is an example of which method/property?
a.) distributive property
b.) collect like terms
c.) FOIL
d.) vertical multiplication

Answer 1

I believe the correct answer is B. The equation given above is an example of "collect like terms" method. When simplifying terms that has addition or subtraction as operations we only add or subtract like terms and it is showed in the equation above. The terms 9x^2 and -2x^2 were added.
