Not sure what your equation is... but here are the two interpretations that I believe you meant... This one... 7x2 + 3x = 0 x(7x+3) = 0 x = 0 and -3/7 Or this one... 7x/2 + 3x=0 7x+6x=0 13x=0 x= 0

3x + 2 = 0 3x = -2 x = -2/3

x = 0

x = y = 0 ?

-2

x2-5-4x2+3x = 0 -3x2+3x-5 = 0 or as 3x2-3x+5 = 0

3x + 2 = 0 3x = -2 x = -2/3

x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.

the answer is -3x = 0

x = 0

x = y = 0 ?

-2

5x = 3x+1000+0 5x-3x = 1000 2x = 1000 x = 500

6-3x+12=0 6+12-3x=0 18-3x=0 18=3x x=6

7x2-10x+3=0 (7x-3)(x-1)=0

x^2 + 3x + 7 = 6x + 18 x^2 - 3x - 11 = 0
