3 n^{2} - 8 n - 26 = 9

n = 5, n = - \frac{7}{3}

Decimal Notation

n = 5, n = - 2.33333 \dots

Solution steps

3 n^{2} - 8 n - 26 = 9

Move

9

to the left side

3 n^{2} - 8 n - 35 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 \cdot 3 ( - 35 )}{2 \cdot 3}

(- 8)^{2} - 4 \cdot 3 (- 35) = 22

n_{1, 2} = \frac{- ( - 8 ) \pm 22}{2 \cdot 3}

Separate the solutions

n_{1} = \frac{- ( - 8 ) + 22}{2 \cdot 3}, n_{2} = \frac{- ( - 8 ) - 22}{2 \cdot 3}

n = \frac{- ( - 8 ) + 22}{2 \cdot 3} : 5

n = \frac{- ( - 8 ) - 22}{2 \cdot 3} : - \frac{7}{3}

The solutions to the quadratic equation are:

n = 5, n = - \frac{7}{3}

x, x^{2} + y^{2} = a^{2}

x^{2} - 4 x - 7 x + (x - 1)^{2} = 7 + 8 - 3 x

2 n^{2} + 6 n - 4 = 0

x, y^{3} - 9 y^{2} + 15 y = x^{2} + 10 x - 8

(x - 6)^{2} = 5
