n^{2} - 3 n - 10 = 0

n = 5, n = - 2

Solution steps

n^{2} - 3 n - 10 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- ( - 3 ) \pm ( - 3 ) ^{2} - 4 \cdot 1 \cdot ( - 10 )}{2 \cdot 1}

(- 3)^{2} - 4 \cdot 1 \cdot (- 10) = 7

n_{1, 2} = \frac{- ( - 3 ) \pm 7}{2 \cdot 1}

Separate the solutions

n_{1} = \frac{- ( - 3 ) + 7}{2 \cdot 1}, n_{2} = \frac{- ( - 3 ) - 7}{2 \cdot 1}

n = \frac{- ( - 3 ) + 7}{2 \cdot 1} : 5

n = \frac{- ( - 3 ) - 7}{2 \cdot 1} : - 2

The solutions to the quadratic equation are:

n = 5, n = - 2

400 - x^{2} = 0

x, 0 = a x^{2} + b x + c

9 x^{2} - 6 = 0

x^{2} + 14 x + 3

- 3 x^{2} + 6 x - 15 = 0
