Full solution

Q. Use the Fundamental Theorem of Algebra to find the number of complex roots of the polynomial, including any repeated roots. \newlinex4+20x18x^4 + 20x - 18\newline____
  1. Find Degree: Look at the polynomial x4+20x18x^4 + 20x - 18 and find the highest power of xx.\newlineDegree of the polynomial: 44.
  2. Fundamental Theorem of Algebra: According to the Fundamental Theorem of Algebra, a polynomial of degree nn has exactly nn complex roots.\newlineSo, the polynomial x4+20x18x^4 + 20x - 18 has 44 complex roots.
