y^{2} + 28 y - 27 = 0

y = - 14 + 223, y = - 14 - 223

Decimal Notation

y = 0.93318 \dots, y = - 28.93318 \dots

Solution steps

y^{2} + 28 y - 27 = 0

Solve with the quadratic formula

y_{1, 2} = \frac{- 28 \pm 2 8 ^{2} - 4 \cdot 1 \cdot ( - 27 )}{2 \cdot 1}

2 8^{2} - 4 \cdot 1 \cdot (- 27) = 2223

y_{1, 2} = \frac{- 28 \pm 2 223}{2 \cdot 1}

Separate the solutions

y_{1} = \frac{- 28 + 2 223}{2 \cdot 1}, y_{2} = \frac{- 28 - 2 223}{2 \cdot 1}

y = \frac{- 28 + 2 223}{2 \cdot 1} : - 14 + 223

y = \frac{- 28 - 2 223}{2 \cdot 1} : - 14 - 223

The solutions to the quadratic equation are:

y = - 14 + 223, y = - 14 - 223

x + 7 > 15 and - 3 x + 4 \geq 7

2^{1.5}

3 x^{2} - 5 x = 12

∣ x - 2 ∣ - 2 = 4

- 1 \leq \frac{4 x - 6}{- 3} \leq 0
