We are asked in this problem to find the real root of the polynomial f(x) = x3 + 0.5x2 + 4.5. in this case, to find the root of the equation, we equate the equation to zero. <span>f(x) = x³ + 0.5x² + 4.5 = 0 2x3 + x^2 + 9 = 0 </span><span>x1=−1.83557 </span>x2=0.66779+1.41619∗i x3=0.66779−1.41619∗i
Answer: 5 pounds of ground beef ( don't see second :-( )
