0 = 2 x^{2} - 2 x - 760

x = 20, x = - 19

Solution steps

0 = 2 x^{2} - 2 x - 760

Switch sides

2 x^{2} - 2 x - 760 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 2 ) \pm ( - 2 ) ^{2} - 4 \cdot 2 ( - 760 )}{2 \cdot 2}

(- 2)^{2} - 4 \cdot 2 (- 760) = 78

x_{1, 2} = \frac{- ( - 2 ) \pm 78}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- ( - 2 ) + 78}{2 \cdot 2}, x_{2} = \frac{- ( - 2 ) - 78}{2 \cdot 2}

x = \frac{- ( - 2 ) + 78}{2 \cdot 2} : 20

x = \frac{- ( - 2 ) - 78}{2 \cdot 2} : - 19

The solutions to the quadratic equation are:

x = 20, x = - 19

5 [- 7 x - 6 + 5 (x + 1)] = 7 x - 3

10 > 16 - 1.2 h

\frac{1}{4} + \frac{1}{10}

6 x^{2} + 78 x + 240 = 0

X + 1 = 2
