100 - 80 x + 12 x^{2} = 0

x = 5, x = \frac{5}{3}

Decimal Notation

x = 5, x = 1.66666 \dots

Solution steps

100 - 80 x + 12 x^{2} = 0

Write in the standard form

a x^{2} + b x + c = 0

12 x^{2} - 80 x + 100 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 80 ) \pm ( - 80 ) ^{2} - 4 \cdot 12 \cdot 100}{2 \cdot 12}

(- 80)^{2} - 4 \cdot 12 \cdot 100 = 40

x_{1, 2} = \frac{- ( - 80 ) \pm 40}{2 \cdot 12}

Separate the solutions

x_{1} = \frac{- ( - 80 ) + 40}{2 \cdot 12}, x_{2} = \frac{- ( - 80 ) - 40}{2 \cdot 12}

x = \frac{- ( - 80 ) + 40}{2 \cdot 12} : 5

x = \frac{- ( - 80 ) - 40}{2 \cdot 12} : \frac{5}{3}

The solutions to the quadratic equation are:

x = 5, x = \frac{5}{3}

14400 = x^{2} - 180 x + 20000

6 x^{2} + 13 = - 11 x + 9

5 x^{2} - 60 x + 100 = 0

- 3 x^{2} - 4 x - 1 = 0

- 12 x^{2} - 8 x = 0
