3 x^{2} - 4.4 x - 6.9 = 0

x = \frac{22 + 2554}{30}, x = \frac{22 - 2554}{30}

Decimal Notation

x = 2.41790 \dots, x = - 0.95123 \dots

Solution steps

3 x^{2} - 4.4 x - 6.9 = 0

Multiply both sides by

10

30 x^{2} - 44 x - 69 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 44 ) \pm ( - 44 ) ^{2} - 4 \cdot 30 ( - 69 )}{2 \cdot 30}

(- 44)^{2} - 4 \cdot 30 (- 69) = 22554

x_{1, 2} = \frac{- ( - 44 ) \pm 2 2554}{2 \cdot 30}

Separate the solutions

x_{1} = \frac{- ( - 44 ) + 2 2554}{2 \cdot 30}, x_{2} = \frac{- ( - 44 ) - 2 2554}{2 \cdot 30}

x = \frac{- ( - 44 ) + 2 2554}{2 \cdot 30} : \frac{22 + 2554}{30}

x = \frac{- ( - 44 ) - 2 2554}{2 \cdot 30} : \frac{22 - 2554}{30}

The solutions to the quadratic equation are:

x = \frac{22 + 2554}{30}, x = \frac{22 - 2554}{30}

(x + 11)^{2} = 121

9^{2} + 2^{2} = c^{2}

2644.6 = 0.68 \cdot 2.14 \cdot 100 \cdot x \cdot (9.5 - 0.4 \cdot x)

70 x^{2} + 1884.96 x - 320443.2 = 0

x, (\frac{x}{2})^{2} π = 900
