It is: 4x squared
8x^2 + 6x - 5 = 8x^2 + 10x - 4x - 5 = 2x * (4x + 5) - (4x + 5) = (2x -1) * (4x + 5)
(2x+3)(2x+4)
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.
4x - 7 = 2x + 5 2x - 7 = 5 2x = 12 x = 6.

(2x-1)(2x-1) = 4x^2 -4x + 1
There is no rational factorisation.

(2x - 1)(4x + 1)
It is: 4x squared
(2x - 1)(2x + 1)
8x^2 + 6x - 5 = 8x^2 + 10x - 4x - 5 = 2x * (4x + 5) - (4x + 5) = (2x -1) * (4x + 5)
8x2 + 6x - 9 = 8x2 + 12x - 6x - 9 = 4x(2x + 3) - 3(2x + 3) = (2x + 3)(4x - 3)
