x^{2} - 4 x - 70 = 0

x = 2 + 74, x = 2 - 74

Solution steps

x^{2} - 4 x - 70 = 0

Solve with the quadratic formula

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

(- 4)^{2} - 4 \cdot 1 \cdot (- 70) = 274

x_{1, 2} = \frac{- ( - 4 ) \pm 2 74}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 4 ) + 2 74}{2 \cdot 1}, x_{2} = \frac{- ( - 4 ) - 2 74}{2 \cdot 1}

x = \frac{- ( - 4 ) + 2 74}{2 \cdot 1} : 2 + 74

x = \frac{- ( - 4 ) - 2 74}{2 \cdot 1} : 2 - 74

The solutions to the quadratic equation are:

x = 2 + 74, x = 2 - 74

(3 x - 1)^{2} + 12 x - 4 = 0

\frac{4 ^{9}}{4 ^{5}}

\frac{3}{4} x + 1 < 4

\frac{1}{2} (- 2)^{2} - 6 \times \frac{2}{3} + 6

25 x^{2} + 40 x y + 16 y^{2}
