a^{2} + 5 a - 8 = 0

a = \frac{- 5 + 57}{2}, a = \frac{- 5 - 57}{2}

Decimal Notation

a = 1.27491 \dots, a = - 6.27491 \dots

Solution steps

a^{2} + 5 a - 8 = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 \cdot 1 \cdot ( - 8 )}{2 \cdot 1}

5^{2} - 4 \cdot 1 \cdot (- 8) = 57

a_{1, 2} = \frac{- 5 \pm 57}{2 \cdot 1}

Separate the solutions

a_{1} = \frac{- 5 + 57}{2 \cdot 1}, a_{2} = \frac{- 5 - 57}{2 \cdot 1}

a = \frac{- 5 + 57}{2 \cdot 1} : \frac{- 5 + 57}{2}

a = \frac{- 5 - 57}{2 \cdot 1} : \frac{- 5 - 57}{2}

The solutions to the quadratic equation are:

a = \frac{- 5 + 57}{2}, a = \frac{- 5 - 57}{2}

x^{2} = 2

x^{2} + 14 x - 5 = 0

(3 x - 4) (x + 1) = - 2

30 x^{2} - 47 x + 14 = 0

2 5^{2} = 7^{2} + x^{2}
