Practice problem
Which of the following is the simplest factorization of x4+x3−x2x^4 + x^3 - x^2x4+x3−x2?
x(x3+x2−x)x(x^3 + x^2 - x)x(x3+x2−x)
x3(x+1−1x)x^3(x + 1 - \frac{1}{x})x3(x+1−x1)
x2(x2+x−1)x^2(x^2 + x - 1)x2(x2+x−1)
x4(1+1x−1x2)x^4(1+ \frac{1}{x} - \frac{1}{x^2})x4(1+x1−x21)
Type a concept, like “slope” or “photosynthesis”.
