5x5 - x - 5
(3x-2)(2x+7) is the same as 6x^2 +17x -14 when the brackets are multiplied out
5x * 2x = 10x^2
4x + 2 +2x - 6 = 0 6x -4 = 0 +4 +4 6x=4 x= 4/6 x=2/3
x multiplied by 2 equals to 2x.
14
The solution to the equation 2x plus 2 is 2(x + 1).
(3x-2)(2x+7) is the same as 6x^2 +17x -14 when the brackets are multiplied out
2x + 4 = 2 2x = -2 x = -1
-2 to the 4th power is 16.
If that was 2x^2 + 5x + 2, it would factor to (2x + 1)(x + 2)
(2x + 1)(x + 2)
