a^{2} - 13 a - 62 = 0

a = \frac{13 + 417}{2}, a = \frac{13 - 417}{2}

Decimal Notation

a = 16.71028 \dots, a = - 3.71028 \dots

Solution steps

a^{2} - 13 a - 62 = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- ( - 13 ) \pm ( - 13 ) ^{2} - 4 \cdot 1 \cdot ( - 62 )}{2 \cdot 1}

(- 13)^{2} - 4 \cdot 1 \cdot (- 62) = 417

a_{1, 2} = \frac{- ( - 13 ) \pm 417}{2 \cdot 1}

Separate the solutions

a_{1} = \frac{- ( - 13 ) + 417}{2 \cdot 1}, a_{2} = \frac{- ( - 13 ) - 417}{2 \cdot 1}

a = \frac{- ( - 13 ) + 417}{2 \cdot 1} : \frac{13 + 417}{2}

a = \frac{- ( - 13 ) - 417}{2 \cdot 1} : \frac{13 - 417}{2}

The solutions to the quadratic equation are:

a = \frac{13 + 417}{2}, a = \frac{13 - 417}{2}

x^{2} + 6 x - 41 = 6 x - 56 x - 5

3 y^{2} - 11 y + 10 = 0

(4 a - 7) (3 a + 8) = 0

x, 4 x^{2} = y^{2}

8000 + 55 x - 0.25 x^{2} = 9000
