If 1 is the zero of the polynomial x2-7x-8
WebA polynomial is a mathematical expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, and multiplication. Polynomials are often written in the form: a₀ + a₁x + a₂x² + a₃x³ + ... + aₙxⁿ, where the a's are coefficients and x is the variable. How do you identify a polynomial?

Since we know x=3 x = 3 and x= {-2} x = −2 are solutions to g (x)=0 g(x) = 0, then \tealD3 3 and \tealD {-2} −2 are zeros of the function g g. Finally, the x x -intercepts of the graph of y=g (x) y = g(x) satisfy the equation 0=g (x) 0 = g(x), which was solved above.
