you do (245x)
-5
4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)
10x - 5 = 2510x = 30x = 3
24
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
-5
-5
-5
5(3-2x)
x^2 - 10 x + 25 = (x - 5)(x - 5)
(x-7)(x-3)
It is 2(2x+3) when factorised
4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)
8x2 - 10x - 3 = (2x - 3)(4x + 1)
If you mean: -10x+4-10x+5 then it is 9-20x when simplified

10x - 5 = 2510x = 30x = 3
