7 a^{2} - 29 a - 30 = 0

a = 5, a = - \frac{6}{7}

Decimal Notation

a = 5, a = - 0.85714 \dots

Solution steps

7 a^{2} - 29 a - 30 = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- ( - 29 ) \pm ( - 29 ) ^{2} - 4 \cdot 7 ( - 30 )}{2 \cdot 7}

(- 29)^{2} - 4 \cdot 7 (- 30) = 41

a_{1, 2} = \frac{- ( - 29 ) \pm 41}{2 \cdot 7}

Separate the solutions

a_{1} = \frac{- ( - 29 ) + 41}{2 \cdot 7}, a_{2} = \frac{- ( - 29 ) - 41}{2 \cdot 7}

a = \frac{- ( - 29 ) + 41}{2 \cdot 7} : 5

a = \frac{- ( - 29 ) - 41}{2 \cdot 7} : - \frac{6}{7}

The solutions to the quadratic equation are:

a = 5, a = - \frac{6}{7}
