3x^2-72x+324=0

Solution

3 x^{2} - 72 x + 324 = 0

Solution

x = 18, x = 6

Solution steps

3 x^{2} - 72 x + 324 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 72 ) \pm ( - 72 ) ^{2} - 4 \cdot 3 \cdot 324}{2 \cdot 3}

(- 72)^{2} - 4 \cdot 3 \cdot 324 = 36

x_{1, 2} = \frac{- ( - 72 ) \pm 36}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- ( - 72 ) + 36}{2 \cdot 3}, x_{2} = \frac{- ( - 72 ) - 36}{2 \cdot 3}

x = \frac{- ( - 72 ) + 36}{2 \cdot 3} : 18

x = \frac{- ( - 72 ) - 36}{2 \cdot 3} : 6

The solutions to the quadratic equation are:

x = 18, x = 6
