It is: 4x squared
7x2 -4x -5x2 +2x = 2x2 -2x
(2x+3)(2x+4)
The expression 2x squared plus x squared can be simplified by combining like terms. When we add 2x squared and x squared, we get 3x squared. Therefore, the simplified expression is 3x 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.

(2x + 1)(x + 2)
(2x+10)(x+4)
Yes it is. The thing that makes it a quadratic equation is that "x squared" in there.
