Solve the quadratic:

n^{2}-6n+1 = 0

a = 1, b = -6, c = 1

n = | -b ± √b^{2} - 4ac |

2a |

-b = -(-6)

-b = 6

Δ = b^{2} - 4ac:

Δ = -6^{2} - 4 x 1 x 1

Δ = 36 - 4

Δ = 32 <--- Discriminant

Since Δ > 0, we expect two real roots.

√Δ = √(32)

√Δ = 4√2

Numerator 1 = -b + √Δ

Numerator 1 = 6 + 4√2

Numerator 2 = -b - √Δ

Numerator 2 = 6 - 4√2

Denominator = 2 * a

Denominator = 2 * 1

Denominator = 2

Solution 1 = | Numerator 1 |

Denominator |

Solution 1 =;(6 + 4√2)/2

6, 2, and 4 are all divisible by 3

Dividing them all by 2, we get:

3, 1, and 2

Solution 1 = (3 . 2√2)/1

Solution 2 = | Numerator 2 |

Denominator |

Solution 2 = (6 - 4√2)/2

6, 2, and 4 are all divisible by 2

Dividing them all by 2, we get: 3, 1, and 2

Solution 2 = (3 - 2√2)/1

(Solution 1, Solution 2) = ((3 . 2√2)/1, (3 - 2√2)/1)

(Solution 1, Solution 2) = ((3 . 2√2)/1, (3 - 2√2)/1)

(Solution 1, Solution 2) = ((3 . 2√2)/1, (3 - 2√2)/1)
