x^{2} + 16 x = 1555

x = - 8 + 1619, x = - 8 - 1619

Decimal Notation

x = 32.23679 \dots, x = - 48.23679 \dots

Solution steps

x^{2} + 16 x = 1555

Move

1555

to the left side

x^{2} + 16 x - 1555 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 16 \pm 1 6 ^{2} - 4 \cdot 1 \cdot ( - 1555 )}{2 \cdot 1}

1 6^{2} - 4 \cdot 1 \cdot (- 1555) = 21619

x_{1, 2} = \frac{- 16 \pm 2 1619}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 16 + 2 1619}{2 \cdot 1}, x_{2} = \frac{- 16 - 2 1619}{2 \cdot 1}

x = \frac{- 16 + 2 1619}{2 \cdot 1} : - 8 + 1619

x = \frac{- 16 - 2 1619}{2 \cdot 1} : - 8 - 1619

The solutions to the quadratic equation are:

x = - 8 + 1619, x = - 8 - 1619

y^{2} = 15 y

3 k^{2} + 9 k - 20 = 2 k

h^{2} + 19 h = 0

3 x^{2} - 10 x = - 7

y^{2} = - 15
