20 n^{2} - 65 n - 175 = 0

n = 5, n = - \frac{7}{4}

Decimal Notation

n = 5, n = - 1.75

Solution steps

20 n^{2} - 65 n - 175 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- ( - 65 ) \pm ( - 65 ) ^{2} - 4 \cdot 20 ( - 175 )}{2 \cdot 20}

(- 65)^{2} - 4 \cdot 20 (- 175) = 135

n_{1, 2} = \frac{- ( - 65 ) \pm 135}{2 \cdot 20}

Separate the solutions

n_{1} = \frac{- ( - 65 ) + 135}{2 \cdot 20}, n_{2} = \frac{- ( - 65 ) - 135}{2 \cdot 20}

n = \frac{- ( - 65 ) + 135}{2 \cdot 20} : 5

n = \frac{- ( - 65 ) - 135}{2 \cdot 20} : - \frac{7}{4}

The solutions to the quadratic equation are:

n = 5, n = - \frac{7}{4}

∣ 5 x - 4 ∣ = ∣ 3 x - 2 ∣

x^{4} + x^{2} + 1 = 0

2 x - 5 = 3 (x + 2) - 1

\frac{7}{9 z ^{3} y} - \frac{1}{21 z ^{2} y}

(k - 4) (k + 5) = 0
