3 n^{2} + 7 n - 20 = 0

n = \frac{5}{3}, n = - 4

Decimal Notation

n = 1.66666 \dots, n = - 4

Solution steps

3 n^{2} + 7 n - 20 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 \cdot 3 ( - 20 )}{2 \cdot 3}

7^{2} - 4 \cdot 3 (- 20) = 17

n_{1, 2} = \frac{- 7 \pm 17}{2 \cdot 3}

Separate the solutions

n_{1} = \frac{- 7 + 17}{2 \cdot 3}, n_{2} = \frac{- 7 - 17}{2 \cdot 3}

n = \frac{- 7 + 17}{2 \cdot 3} : \frac{5}{3}

n = \frac{- 7 - 17}{2 \cdot 3} : - 4

The solutions to the quadratic equation are:

n = \frac{5}{3}, n = - 4

s, s^{2} + 4 = 0

y, (x - 5)^{2} + (y - 5)^{2} = 25

1 - 1.3 x + 0.4 x^{2} = 0

- y^{2} + 2 y

(y - 3)^{2} = 4
