$${ x }^{ 2 } +26x+6$$

Factor

$$\left(x-\left(-\sqrt{163}-13\right)\right)\left(x-\left(\sqrt{163}-13\right)\right)$$

Steps Using the Quadratic Formula

Quadratic polynomial can be factored using the transformation ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right), where x_{1} and x_{2} are the solutions of the quadratic equation ax^{2}+bx+c=0.

$$x^{2}+26x+6=0$$

All equations of the form ax^{2}+bx+c=0 can be solved using the quadratic formula: \frac{-b±\sqrt{b^{2}-4ac}}{2a}. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.

$$x=\frac{-26±\sqrt{26^{2}-4\times 6}}{2}$$

Square 26.

$$x=\frac{-26±\sqrt{676-4\times 6}}{2}$$

Multiply -4 times 6.

$$x=\frac{-26±\sqrt{676-24}}{2}$$

Add 676 to -24.

$$x=\frac{-26±\sqrt{652}}{2}$$

Take the square root of 652.

$$x=\frac{-26±2\sqrt{163}}{2}$$

Now solve the equation x=\frac{-26±2\sqrt{163}}{2} when ± is plus. Add -26 to 2\sqrt{163}.

$$x=\frac{2\sqrt{163}-26}{2}$$

Divide -26+2\sqrt{163} by 2.

$$x=\sqrt{163}-13$$

Now solve the equation x=\frac{-26±2\sqrt{163}}{2} when ± is minus. Subtract 2\sqrt{163} from -26.

$$x=\frac{-2\sqrt{163}-26}{2}$$

Divide -26-2\sqrt{163} by 2.

$$x=-\sqrt{163}-13$$

Factor the original expression using ax^{2}+bx+c=a\left(x-x_{1}\right)\left(x-x_{2}\right). Substitute -13+\sqrt{163} for x_{1} and -13-\sqrt{163} for x_{2}.

$$x^{2}+26x+6=\left(x-\left(\sqrt{163}-13\right)\right)\left(x-\left(-\sqrt{163}-13\right)\right)$$

Evaluate

$$x^{2}+26x+6$$
