7x(x - 17) = -50x
7x² - 119x = -50x
7x² - 69x = 0
x(7x - 69) = 0
x = 0
7x - 69 = 0
7x = 69
x = 69/7
x = {0, 69/7}

7x (x-17) = -50x
7x² – 119x + 50x = 0
7x² – 69x = 0
x(7x – 69) = 0
x = 0, 69/7

quadratic form is ax squared + bx + c=y so let *2* equal squared becuase idk how to do a square symbol on the computer,
7x(x-17)+50x=0 so that would be 7x*2* -119x+50x=0 which would simplify to be 7x*2*-69x=0
there us a 60% chance that that is right...
