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

x = \frac{- a + a ^{2} + 32}{2}, x = \frac{- a - a ^{2} + 32}{2}

Solution steps

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

Solve with the quadratic formula

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

Simplify

a^{2} - 4 \cdot 1 \cdot (- 8) : a^{2} + 32

x_{1, 2} = \frac{- a \pm a ^{2} + 32}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- a + a ^{2} + 32}{2 \cdot 1}, x_{2} = \frac{- a - a ^{2} + 32}{2 \cdot 1}

x = \frac{- a + a ^{2} + 32}{2 \cdot 1} : \frac{- a + a ^{2} + 32}{2}

x = \frac{- a - a ^{2} + 32}{2 \cdot 1} : \frac{- a - a ^{2} + 32}{2}

The solutions to the quadratic equation are:

x = \frac{- a + a ^{2} + 32}{2}, x = \frac{- a - a ^{2} + 32}{2}

3 x^{2} - 2 x - 2 = 0

5 y^{2} + 1 = 21

x^{2} - 22 x + 72 = 0

0 = 3 - x^{2}

x, x^{2} - 2 k x + 3 k = 0
