x^{2} - 7 x - 78 = 0

x = 13, x = - 6

Solution steps

x^{2} - 7 x - 78 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 \cdot 1 \cdot ( - 78 )}{2 \cdot 1}

(- 7)^{2} - 4 \cdot 1 \cdot (- 78) = 19

x_{1, 2} = \frac{- ( - 7 ) \pm 19}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 7 ) + 19}{2 \cdot 1}, x_{2} = \frac{- ( - 7 ) - 19}{2 \cdot 1}

x = \frac{- ( - 7 ) + 19}{2 \cdot 1} : 13

x = \frac{- ( - 7 ) - 19}{2 \cdot 1} : - 6

The solutions to the quadratic equation are:

x = 13, x = - 6

3 (4 b - 3) \leq 4 (b + 1) - 5 b

m^{2} + m - 6

4 \frac{405 x ^{3} y ^{3}}{5 x ^{- 1} y}

3 (x) + (14 - x) = 2 \cdot x (2 x - 21)

\frac{40 i}{3 + i}
