(2x + 1)(2x + 1) or (2x + 1)2 so x = -0.5
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 ?
2x(2x - 1)
-2x=-4x*24 x=12
4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11
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)(2x + 1) or (2x + 1)2 so x = -0.5
7x2 -4x -5x2 +2x = 2x2 -2x

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 ?
-x2+2x
It is: 4x squared
2x(2x - 1)
2x squared can best be describe as some variable being double and then squared.
(2x-1)(2x-1) = 4x^2 -4x + 1
2x
If: y = x^2 -2x +4 and y = 2x^2 -4x +4 Then: 2x^2 -4x +4 = x^2 -2x +4 Transposing terms: x^2 -2x = 0 Factorizing: (x-2)(x+0) => x = 2 or x = 0 Therefore by substitution points of intersect are at: (2, 4) and (0, 4)
