49 s^{2} + 70 s = - 25

s = - \frac{5}{7}

Decimal Notation

s = - 0.71428 \dots

Solution steps

49 s^{2} + 70 s = - 25

Move

25

to the left side

49 s^{2} + 70 s + 25 = 0

Solve with the quadratic formula

s_{1, 2} = \frac{- 70 \pm 7 0 ^{2} - 4 \cdot 49 \cdot 25}{2 \cdot 49}

7 0^{2} - 4 \cdot 49 \cdot 25 = 0

s_{1, 2} = \frac{- 70 \pm 0}{2 \cdot 49}

s = \frac{- 70}{2 \cdot 49}

\frac{- 70}{2 \cdot 49} = - \frac{5}{7}

s = - \frac{5}{7}

The solution to the quadratic equation is:

s = - \frac{5}{7}

2 x^{2} - 30 x + 100 = 0

x^{2} - 75 x + 20 = 0

2 (x - 4) (x - 8) = - 1

0 = 2 x^{2} + 7 x - 15

- 4.9 x^{2} + 10 x + 2 = 0
