7 = 0.003 x^{2} + 0.001 x

x = \frac{- 1 + 84001}{6}, x = \frac{- 1 - 84001}{6}

Decimal Notation

x = 48.13821 \dots, x = - 48.47154 \dots

Solution steps

7 = 0.003 x^{2} + 0.001 x

Multiply both sides by

1000

7000 = 3 x^{2} + x

Switch sides

3 x^{2} + x = 7000

Move

7000

to the left side

3 x^{2} + x - 7000 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 1 \pm 1 ^{2} - 4 \cdot 3 ( - 7000 )}{2 \cdot 3}

1^{2} - 4 \cdot 3 (- 7000) = 84001

x_{1, 2} = \frac{- 1 \pm 84001}{2 \cdot 3}

Separate the solutions

x_{1} = \frac{- 1 + 84001}{2 \cdot 3}, x_{2} = \frac{- 1 - 84001}{2 \cdot 3}

x = \frac{- 1 + 84001}{2 \cdot 3} : \frac{- 1 + 84001}{6}

x = \frac{- 1 - 84001}{2 \cdot 3} : \frac{- 1 - 84001}{6}

The solutions to the quadratic equation are:

x = \frac{- 1 + 84001}{6}, x = \frac{- 1 - 84001}{6}

x^{2} - 0.9 x - 1.52 = 0

3 X^{2} - 3 = 0

x, f (x + 2 - 2) = 2 (x + 2)^{2} - 3 (x + 2) - 1

x, y^{2} = - 4 p x^{2}

x^{2} - 6 x + 9 = 10
