A complex fraction is. Fraction at a whole number
Ok so you have 4, x^6 / 2, x^4. Now divide the coefficient so 4/2=2. So 2 x^6/x^4, now subtract the numerator by the denominator so x^6-x^4=x^2 so now you have 2x^2
Answer: 2x^2
5x2 + 15x + 4x + 12
5x(x + 3) +4(x + 3)
(x+3)(5x+4)
The answer is f12 submit 8765
