2x(x-3)+x=-3(6-x)+2x^2

2 x (x - 3) + x = - 3 (6 - x) + 2 x^{2}

x = \frac{9}{4}

Decimal Notation

x = 2.25

Solution steps

2 x (x - 3) + x = - 3 (6 - x) + 2 x^{2}

Expand

2 x (x - 3) : 2 x^{2} - 6 x

2 x^{2} - 6 x + x = - 3 (6 - x) + 2 x^{2}

Add similar elements:

- 6 x + x = - 5 x

2 x^{2} - 5 x = - 3 (6 - x) + 2 x^{2}

Expand

- 3 (6 - x) : - 18 + 3 x

2 x^{2} - 5 x = - 18 + 3 x + 2 x^{2}

Subtract

3 x + 2 x^{2}

from both sides

2 x^{2} - 5 x - (3 x + 2 x^{2}) = - 18 + 3 x + 2 x^{2} - (3 x + 2 x^{2})

Simplify

- 8 x = - 18

Divide both sides by

- 8

x = \frac{9}{4}

x - 16 = - 8

0.07 y + 0.13 (3000 - y) = 0.44 y

a^{1} = 5

f = 2 (4)

2 x + 4 = 1
