Solve 1^2+c^23

$$1 ^ { 2 } + c ^ { 23 }$$

Factor

$$\left(c+1\right)\left(c^{22}-c^{21}+c^{20}-c^{19}+c^{18}-c^{17}+c^{16}-c^{15}+c^{14}-c^{13}+c^{12}-c^{11}+c^{10}-c^{9}+c^{8}-c^{7}+c^{6}-c^{5}+c^{4}-c^{3}+c^{2}-c+1\right)$$

Solution Steps

Multiply and combine like terms.

$$c^{23}+1$$

By Rational Root Theorem, all rational roots of a polynomial are in the form \frac{p}{q}, where p divides the constant term 1 and q divides the leading coefficient 1. One such root is -1. Factor the polynomial by dividing it by c+1. Polynomial c^{22}-c^{21}+c^{20}-c^{19}+c^{18}-c^{17}+c^{16}-c^{15}+c^{14}-c^{13}+c^{12}-c^{11}+c^{10}-c^{9}+c^{8}-c^{7}+c^{6}-c^{5}+c^{4}-c^{3}+c^{2}-c+1 is not factored since it does not have any rational roots.

$$\left(c+1\right)\left(c^{22}-c^{21}+c^{20}-c^{19}+c^{18}-c^{17}+c^{16}-c^{15}+c^{14}-c^{13}+c^{12}-c^{11}+c^{10}-c^{9}+c^{8}-c^{7}+c^{6}-c^{5}+c^{4}-c^{3}+c^{2}-c+1\right)$$

Evaluate

$$c^{23}+1$$

Solution Steps

Calculate 1 to the power of 2 and get 1.

$$1+c^{23}$$
