She isn't. 4x squared is 4 times (x squared). That is, 4 times (3 squared) = 4 times 9. If you want it to be the square of 4x (which would be the square of 4 times 3, ie, 12), you have to write it as (4x)squared.
x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
y=4x-12-3 is the equation of a straight line. It does not have a vertex. Did you mean y=x squared - 12x - 3 ?
(x, y) = (-3, -3) or (3, 3)
The greatness of 4 squared and 3 squared is expressed by the equation: 16 - 9 which equals 7.3 squared equals 3 x 3 = 94 squared equals 4 x 4 = 1616 - 9 = 7
3 squared=9 3 squared=3*3 3*3=9
It is: 12x2-7x-12 equals (4x+3)(3x-4) when factored

The GCF of 84 and 144 is 12. You must do the prime factorization of each number. The prime factorization of 144 is 2 to the fourth power times 3 squared. The prime factorization of 84 is 2 squared times 7 times 3. You take the least of each common factor which would be 2 squared and 3. Two squared equals 4 and 4 times 3 equals 12, so the GCF is 12.

if x= 3 or -3
(x, y) = (-3, -3) or (3, 3)
If a number is 'squared' it's simply multiplied by itself. for example 3 squared is 3 x 3 which equals 9.
