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.
Seems to us that any value at all can be squared.
93 to the power of two is also known as 3 squared which means 3 X 3= 9
5+3^2-1 = 13 (5+3)^2-1=63
9 is the value of -3 squared
3 squared is 3 x 3 or 9.
-3
If you mean: (x+3) squared = (x+2) squared +11 Then the value of x works out as 3
The vertex of this parabola is at -2 -3 When the y-value is -2 the x-value is -5. The coefficient of the squared term in the parabola's equation is -3.
x = 3/sqrt(2) or 1.5*sqrt(2)
The vertex of this parabola is at -3 -1 When the y-value is 0 the x-value is 4. The coefficient of the squared term in the parabolas equation is 7
