x (2 x - 2) = 760

x = 20, x = - 19

Solution steps

x (2 x - 2) = 760

Expand

x (2 x - 2) : 2 x^{2} - 2 x

2 x^{2} - 2 x = 760

Move

760

to the left side

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

z^{2} + 28 = 11 z

384 x^{4} y^{3}

∣ 2 x + 4 ∣ > 7

\frac{15 !}{3 ! ( 15 - 3 ) !}
