10x%5E2=9x%2B9, EQN 1
10x%5E2-9x-9=0 -------> it follows quadratic eqn: ax%5E2%2Bbx%2Bc=0
where---->system%28a=10%2Cb=-9%2Cc=-9%29
Plug in the values to quadratic eqn:
x=%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F%282a%29
ANSWERS:
highlight%28x=3%2F2%29;highlight%28x=-3%2F5%29
Check via EQN 1;
10%283%2F2%29%5E2=9%283%2F2%29%2B9
10%289%2F4%29=%2827%2F2%29%2B9
90%2F4=%2827%2B18%29%2F2
45%2F2=45%2F2
