Answer 3

3x+6+5x/x^2+2x=2

Answer 4

3x+6+5x=2(x^2+2)

Answer 5

thanks

Answer 6

so it would be 2x^2-4x-6?

Answer 7

3x+6+5x=2x^2+4
-2x^2+7x+2=0
use the formula \[-b \pm \sqrt{b ^{2}-4ac}/2a\]
a=-2
b=7
c=2
plug in the values.

Answer 8

its 8x and 4 x?

Answer 9

-2x^2 +8x+2

Answer 10

2x^2+4

Answer 13

3x+6+5x=2(x^2+2x)
3x+6+5x=2x^2+4x
-2x^2+3x-4x+5x+6=0
-2x^2+4x+6=0
