a^{2} - 9 a + 2 = 0

a = \frac{9 + 73}{2}, a = \frac{9 - 73}{2}

Decimal Notation

a = 8.77200 \dots, a = 0.22799 \dots

Solution steps

a^{2} - 9 a + 2 = 0

Solve with the quadratic formula

a_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 1 \cdot 2}{2 \cdot 1}

(- 9)^{2} - 4 \cdot 1 \cdot 2 = 73

a_{1, 2} = \frac{- ( - 9 ) \pm 73}{2 \cdot 1}

Separate the solutions

a_{1} = \frac{- ( - 9 ) + 73}{2 \cdot 1}, a_{2} = \frac{- ( - 9 ) - 73}{2 \cdot 1}

a = \frac{- ( - 9 ) + 73}{2 \cdot 1} : \frac{9 + 73}{2}

a = \frac{- ( - 9 ) - 73}{2 \cdot 1} : \frac{9 - 73}{2}

The solutions to the quadratic equation are:

a = \frac{9 + 73}{2}, a = \frac{9 - 73}{2}

x^{2} + (1 - 2 k) x + (k^{2} - k - 2) = 0

x^{2} - 13 x - 420 = 0

x, p (x) = y (x^{2} + 2) - x (y^{2} + 2)

- X^{2} - 2 X + 1 = 0

x, f^{- 1} (x) = 2 - (x - 3)^{2}
