a^{2} - 3 a - 154 = 0

a = 14, a = - 11

Solution steps

a^{2} - 3 a - 154 = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- ( - 3 ) \pm ( - 3 ) ^{2} - 4 \cdot 1 \cdot ( - 154 )}{2 \cdot 1}

(- 3)^{2} - 4 \cdot 1 \cdot (- 154) = 25

a_{1, 2} = \frac{- ( - 3 ) \pm 25}{2 \cdot 1}

Separate the solutions

a_{1} = \frac{- ( - 3 ) + 25}{2 \cdot 1}, a_{2} = \frac{- ( - 3 ) - 25}{2 \cdot 1}

a = \frac{- ( - 3 ) + 25}{2 \cdot 1} : 14

a = \frac{- ( - 3 ) - 25}{2 \cdot 1} : - 11

The solutions to the quadratic equation are:

a = 14, a = - 11

x^{2} - 24 x + 144

v^{2} - 7 v = 0

- \frac{4}{4} + 160% + \frac{1}{5}

\frac{7}{12} - \frac{1}{4}

- x^{2} + 1 \geq 0
