Answer:

D. The equation has a variable multiplied by itself. A squared variable.

Step-by-step explanation:

A quadratic equation will always start with a term being squared. For example, 8x^{2} + 5x + 7 = 44. Another example would be 4x^{2} + 2x - 10 = 12. These are just random numbers, but the equation will always look the same! Hope this helps!

Answer:

D. The equation has a variable multiplied by itself. A squared variable.

Step-by-step explanation:

Yes, they are different. Imagine your random variable takes only the values 0 and 1, with equal probability.

Squaring your value gives 0 and 1 with equal probability;

multiplying by itself gives 0*0,0*1,1*0, and 1*1 with equal probability.

The first has an expected value of .5 the second 0.25
