The number of rational roots of equation x(x + 2)(x2 − 1) − 1 = 0 are/isSelect an answerA0B4C1D2
Question
Solution 1
The given equation is x(x + 2)(x^2 - 1) - 1 = 0.
Let's simplify this equation:
x(x + 2)(x^2 - 1) = 1
x(x^3 - x + 2x - 2) = 1
x^4 - x^2 + 2x^2 - 2x - 1 = 0
x^4 + x^2 - 2x - 1 = 0
This is a quartic equation. The rational root theorem states that any rational root, p/q (where p and q are relative Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
