Answer:
x = 6
Step-by-step explanation:
0 = x^2 -12x + 36 solve by factoring ...or Quadratic Formula
0 = ( x-6)(x-6) shows zeroes ( both of them) are x = 6
Yes, they are. Treat ratios like fractions, simplify them the same way. In 6/36, the GCF (Greatest Common Factor) of the numerator and the denominator is six. So, we divide both sides by six. This gives us 1/6, which is still the same fraction. (Making it proportional)
