Question

After x+2/2 - x+1/3x have been combined using the least common denominator of 6x, what is the numerator?

a. 3x^2 + 4x + 1
b. 3x^2 + 4x - 2
c. -3x^2 - x + 4
d. -x^2 + 3x + 4

Answer 1

i think you should check the options again because it should be 3x^2+4x+2...

cause

((x+2)3x+2(1-x))/6x
=3x^2+6x+2-2x/6x
=3x^2+4x+2/6x

the numerator should be 3x^2+4x+2

@lowcard2 what do you think ?
