5 n^{2} - 30 n + 20 = - n

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

Decimal Notation

n = 5, n = 0.8

Solution steps

5 n^{2} - 30 n + 20 = - n

Move

n

to the left side

5 n^{2} - 29 n + 20 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- ( - 29 ) \pm ( - 29 ) ^{2} - 4 \cdot 5 \cdot 20}{2 \cdot 5}

(- 29)^{2} - 4 \cdot 5 \cdot 20 = 21

n_{1, 2} = \frac{- ( - 29 ) \pm 21}{2 \cdot 5}

Separate the solutions

n_{1} = \frac{- ( - 29 ) + 21}{2 \cdot 5}, n_{2} = \frac{- ( - 29 ) - 21}{2 \cdot 5}

n = \frac{- ( - 29 ) + 21}{2 \cdot 5} : 5

n = \frac{- ( - 29 ) - 21}{2 \cdot 5} : \frac{4}{5}

The solutions to the quadratic equation are:

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

- 34 = 15 - 80 x^{2}

x^{2} - 6 x = 0

5 x^{2} - 3 x = 0

y, x^{2} y = 1

3 y^{2} - 8 y + 4 = 5 y
