15 w^{2} + 28 w + 3 = - 2

w = - \frac{1}{5}, w = - \frac{5}{3}

Decimal Notation

w = - 0.2, w = - 1.66666 \dots

Solution steps

15 w^{2} + 28 w + 3 = - 2

Move

2

to the left side

15 w^{2} + 28 w + 5 = 0

Solve with the quadratic formula

w_{1, 2} = \frac{- 28 \pm 2 8 ^{2} - 4 \cdot 15 \cdot 5}{2 \cdot 15}

2 8^{2} - 4 \cdot 15 \cdot 5 = 22

w_{1, 2} = \frac{- 28 \pm 22}{2 \cdot 15}

Separate the solutions

w_{1} = \frac{- 28 + 22}{2 \cdot 15}, w_{2} = \frac{- 28 - 22}{2 \cdot 15}

w = \frac{- 28 + 22}{2 \cdot 15} : - \frac{1}{5}

w = \frac{- 28 - 22}{2 \cdot 15} : - \frac{5}{3}

The solutions to the quadratic equation are:

w = - \frac{1}{5}, w = - \frac{5}{3}

\frac{x + y}{x - y}
