n^{2} - n - 30 = 0

n = 6, n = - 5

Solution steps

n^{2} - n - 30 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 \cdot 1 \cdot ( - 30 )}{2 \cdot 1}

(- 1)^{2} - 4 \cdot 1 \cdot (- 30) = 11

n_{1, 2} = \frac{- ( - 1 ) \pm 11}{2 \cdot 1}

Separate the solutions

n_{1} = \frac{- ( - 1 ) + 11}{2 \cdot 1}, n_{2} = \frac{- ( - 1 ) - 11}{2 \cdot 1}

n = \frac{- ( - 1 ) + 11}{2 \cdot 1} : 6

n = \frac{- ( - 1 ) - 11}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

n = 6, n = - 5

\frac{7 π}{4} = \frac{3 π}{4} r^{2}

4 p^{2} + 6 = 20 p

24 x - 3 x^{2} = 0

x, x^{2} + y^{2} - (z - 20)^{2} = 0

6 = a^{2} + 8
