2 k^{2} + 22 k = 74

k = \frac{- 11 + 269}{2}, k = - \frac{11 + 269}{2}

Decimal Notation

k = 2.70060 \dots, k = - 13.70060 \dots

Solution steps

2 k^{2} + 22 k = 74

Move

74

to the left side

2 k^{2} + 22 k - 74 = 0

Solve with the quadratic formula

k_{1, 2} = \frac{- 22 \pm 2 2 ^{2} - 4 \cdot 2 ( - 74 )}{2 \cdot 2}

2 2^{2} - 4 \cdot 2 (- 74) = 2269

k_{1, 2} = \frac{- 22 \pm 2 269}{2 \cdot 2}

Separate the solutions

k_{1} = \frac{- 22 + 2 269}{2 \cdot 2}, k_{2} = \frac{- 22 - 2 269}{2 \cdot 2}

k = \frac{- 22 + 2 269}{2 \cdot 2} : \frac{- 11 + 269}{2}

k = \frac{- 22 - 2 269}{2 \cdot 2} : - \frac{11 + 269}{2}

The solutions to the quadratic equation are:

k = \frac{- 11 + 269}{2}, k = - \frac{11 + 269}{2}

x + 11 = \frac{( x - 13 ) ^{2}}{2}

x^{2} + 6 x - 60 = 3 x - 20

2 7^{- \frac{2}{3}}

x^{2} \cdot y^{2}

∣ 3 x - 4 ∣ < 5
