4 n^{2} - 30 n = - 36

n = 6, n = \frac{3}{2}

Decimal Notation

n = 6, n = 1.5

Solution steps

4 n^{2} - 30 n = - 36

Move

36

to the left side

4 n^{2} - 30 n + 36 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- ( - 30 ) \pm ( - 30 ) ^{2} - 4 \cdot 4 \cdot 36}{2 \cdot 4}

(- 30)^{2} - 4 \cdot 4 \cdot 36 = 18

n_{1, 2} = \frac{- ( - 30 ) \pm 18}{2 \cdot 4}

Separate the solutions

n_{1} = \frac{- ( - 30 ) + 18}{2 \cdot 4}, n_{2} = \frac{- ( - 30 ) - 18}{2 \cdot 4}

n = \frac{- ( - 30 ) + 18}{2 \cdot 4} : 6

n = \frac{- ( - 30 ) - 18}{2 \cdot 4} : \frac{3}{2}

The solutions to the quadratic equation are:

n = 6, n = \frac{3}{2}

\frac{1}{2} \cdot 17 \cdot 5

∣ x - 6 ∣ < 4

x (3 x + 1) - 5 (1 - 2 x) = (3 x + 2)^{2} + 1

4 x^{4} + 8 x^{3} - 21 x^{2} - 18 x + 27
