Find all real roots of P(x)=2x4−x3−7x2+3x+3P(x) = 2x^4 - x^3 - 7x^2 + 3x + 3P(x)=2x4−x3−7x2+3x+3 using the Rational Root Theorem. One root is x=3x = 3x=3.
x=3,−1,12,−1x = 3, -1, \frac{1}{2}, -1x=3,−1,21,−1
x=3,1,12,−1x = 3, 1, \frac{1}{2}, -1x=3,1,21,−1
x=3,−1,−12x = 3, -1, -\frac{1}{2}x=3,−1,−21 and one irrational
x=3,1,−32x = 3, 1, -\frac{3}{2}x=3,1,−23
