n^2-12n+27=0

Solution

n^{2} - 12 n + 27 = 0

Solution

n = 9, n = 3

Solution steps

n^{2} - 12 n + 27 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- ( - 12 ) \pm ( - 12 ) ^{2} - 4 \cdot 1 \cdot 27}{2 \cdot 1}

(- 12)^{2} - 4 \cdot 1 \cdot 27 = 6

n_{1, 2} = \frac{- ( - 12 ) \pm 6}{2 \cdot 1}

Separate the solutions

n_{1} = \frac{- ( - 12 ) + 6}{2 \cdot 1}, n_{2} = \frac{- ( - 12 ) - 6}{2 \cdot 1}

n = \frac{- ( - 12 ) + 6}{2 \cdot 1} : 9

n = \frac{- ( - 12 ) - 6}{2 \cdot 1} : 3

The solutions to the quadratic equation are:

n = 9, n = 3
