x(x+4)+x(x+2)=2x^2+12

x (x + 4) + x (x + 2) = 2 x^{2} + 12

x = 2

Solution steps

x (x + 4) + x (x + 2) = 2 x^{2} + 12

Expand

x (x + 4) + x (x + 2) : 2 x^{2} + 6 x

2 x^{2} + 6 x = 2 x^{2} + 12

Move

2 x^{2}

to the left side

6 x = 12

Divide both sides by

6

x = 2

\frac{1}{2} x - 2 = \frac{1}{5}

7 x + 10 + 3 x = 120

x, x - 4 y + 3 = 0

6 (x + 1) = 5 (x + 2)

11 d = 81 - 16 d
