Get support from expert teachers. There is a similar relationship between the number of sign changes in [latex]f\left(-x\right)[/latex] and the number of negative real zeros. Therefore, [latex]f\left(2\right)=25[/latex]. Similarly, if [latex]x-k[/latex]is a factor of [latex]f\left(x\right)[/latex],then the remainder of the Division Algorithm [latex]f\left(x\right)=\left(x-k\right)q\left(x\right)+r[/latex]is 0. Recall that the Division Algorithm states that given a polynomial dividend f(x)and a non-zero polynomial divisor d(x)where the degree ofd(x) is less than or equal to the degree of f(x), there exist unique polynomials q(x)and r(x)such that, [latex]f\left(x\right)=d\left(x\right)q\left(x\right)+r\left(x\right)[/latex], If the divisor, d(x), is x k, this takes the form, [latex]f\left(x\right)=\left(x-k\right)q\left(x\right)+r[/latex], Since the divisor x kis linear, the remainder will be a constant, r. And, if we evaluate this for x =k, we have, [latex]\begin{array}{l}f\left(k\right)=\left(k-k\right)q\left(k\right)+r\hfill \\ \text{}f\left(k\right)=0\cdot q\left(k\right)+r\hfill \\ \text{}f\left(k\right)=r\hfill \end{array}[/latex].
