7x2 -4x -5x2 +2x = 2x2 -2x
It is: 4x squared
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
d/dx 2x^2 = 4x
(2x+3)(2x+4)
7x2 -4x -5x2 +2x = 2x2 -2x
-x2+2x
It is: 4x squared
2x(2x - 1)
(2x-1)(2x-1) = 4x^2 -4x + 1
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
d/dx 2x^2 = 4x
(2x - 1)(2x + 1)
(2x + 5)(2x + 5)
(2x - 3)(2x - 3)
4x[squared]y
The derivative of 2x2 + 4x + 8 is 4x+4.
