4 a^{2} + 5 a - 26 = 0

a = 2, a = - \frac{13}{4}

Decimal Notation

a = 2, a = - 3.25

Solution steps

4 a^{2} + 5 a - 26 = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 \cdot 4 ( - 26 )}{2 \cdot 4}

5^{2} - 4 \cdot 4 (- 26) = 21

a_{1, 2} = \frac{- 5 \pm 21}{2 \cdot 4}

Separate the solutions

a_{1} = \frac{- 5 + 21}{2 \cdot 4}, a_{2} = \frac{- 5 - 21}{2 \cdot 4}

a = \frac{- 5 + 21}{2 \cdot 4} : 2

a = \frac{- 5 - 21}{2 \cdot 4} : - \frac{13}{4}

The solutions to the quadratic equation are:

a = 2, a = - \frac{13}{4}
