WebOct 6, 2024 · We can see that there is a root at x = 2. This means that the polynomial will have a factor of ( x − 2). We can use Synthetic Division to find any other factors. … WebBecause this polynomial has real coefficients, that means that the complex conjugate -i is also a root. So we can factor out (x+i) (x-i)=x²+1 with synthetic division. This gives us (x²+2x+1) (x²+1). Now we can use the quadratic formula to find the roots of x²+2x+1. We get [-2±√ (4-4)]/2= -2/2= -1. gun shops marshall mo

Web👉 Learn how to find all the zeros of a polynomial. A polynomial is an expression of the form ax^n + bx^ (n-1) + . . . + k, where a, b, and k are constants and the exponents are positive... WebSo root is the same thing as a zero, and they're the x-values that make the polynomial equal to zero. So the real roots are the x-values where p of x is equal to zero. So, the x-values that satisfy this are going to be the roots, or the zeros, and we want the real ones. bow valley college job postings
