35 x^{2} - 70 x - 1680 = 0

x = 8, x = - 6

Solution steps

35 x^{2} - 70 x - 1680 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 70 ) \pm ( - 70 ) ^{2} - 4 \cdot 35 ( - 1680 )}{2 \cdot 35}

(- 70)^{2} - 4 \cdot 35 (- 1680) = 490

x_{1, 2} = \frac{- ( - 70 ) \pm 490}{2 \cdot 35}

Separate the solutions

x_{1} = \frac{- ( - 70 ) + 490}{2 \cdot 35}, x_{2} = \frac{- ( - 70 ) - 490}{2 \cdot 35}

x = \frac{- ( - 70 ) + 490}{2 \cdot 35} : 8

x = \frac{- ( - 70 ) - 490}{2 \cdot 35} : - 6

The solutions to the quadratic equation are:

x = 8, x = - 6

m^{2} - 2 m + 6 = 0

x \cdot (8 - 6 \cdot x) + 6 = 3 - x \cdot (2 \cdot x - 4)

186.67 x^{2} - 21333.6 x + 426672 = 0

x, x^{2} + x y + y^{2} - 6 = 0

0 = x^{2} - 7 x + 5
