u^2-9u+18=0

Solution

u^{2} - 9 u + 18 = 0

Solution

u = 6, u = 3

Solution steps

u^{2} - 9 u + 18 = 0

Solve with the quadratic formula

u_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 1 \cdot 18}{2 \cdot 1}

(- 9)^{2} - 4 \cdot 1 \cdot 18 = 3

u_{1, 2} = \frac{- ( - 9 ) \pm 3}{2 \cdot 1}

Separate the solutions

u_{1} = \frac{- ( - 9 ) + 3}{2 \cdot 1}, u_{2} = \frac{- ( - 9 ) - 3}{2 \cdot 1}

u = \frac{- ( - 9 ) + 3}{2 \cdot 1} : 6

u = \frac{- ( - 9 ) - 3}{2 \cdot 1} : 3

The solutions to the quadratic equation are:

u = 6, u = 3
