2 a^{2} - 13 a - 16 = 8

a = 8, a = - \frac{3}{2}

Decimal Notation

a = 8, a = - 1.5

Solution steps

2 a^{2} - 13 a - 16 = 8

Move

8

to the left side

2 a^{2} - 13 a - 24 = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- ( - 13 ) \pm ( - 13 ) ^{2} - 4 \cdot 2 ( - 24 )}{2 \cdot 2}

(- 13)^{2} - 4 \cdot 2 (- 24) = 19

a_{1, 2} = \frac{- ( - 13 ) \pm 19}{2 \cdot 2}

Separate the solutions

a_{1} = \frac{- ( - 13 ) + 19}{2 \cdot 2}, a_{2} = \frac{- ( - 13 ) - 19}{2 \cdot 2}

a = \frac{- ( - 13 ) + 19}{2 \cdot 2} : 8

a = \frac{- ( - 13 ) - 19}{2 \cdot 2} : - \frac{3}{2}

The solutions to the quadratic equation are:

a = 8, a = - \frac{3}{2}

12 x^{2} - 11 x - 15

5 (z + 3.41) = - 7.89 (2 z - 4) - 5.67

m^{2} = 8 m - 15

\frac{- 2}{- 6}

\frac{1}{2} \leq \frac{5}{c} \leq \frac{6}{4}
