2x2-9x+4 = (2x-1)(x-4) when factored
Assuming it's a plus sign, that factors to (2x + 1)(x + 4)
The expression simplifies to: -7x-4
2x+4+7x-4 is the same as 9x
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
2x2-9x+4 = (2x-1)(x-4) when factored
Assuming it's a plus sign, that factors to (2x + 1)(x + 4)
9x-4 = 7x+8 9x-7x = 8+4 2x = 12 x = 6
(3x - 4)(2x^2 + 6x + 5)
The expression simplifies to: -7x-4
2x+4+7x-4 is the same as 9x
-4x-1-3x-4+5 = -7x-1-2x+1+6 -7x = -9x+6 2x = 6 x = 3
answer is 4 7x+19=-2x+55 +2x +2x 9x+19= 0 55 -19 -19 9x = 36 9 9 =4
(2x + 1)(x + 4)
9x squared plus 16 = 0 factored is plus and minus 4/3 i.
1/4 = 3 - 2x - 1/ x + 24 ( 3 - 2x - 1 ) = 1 ( x + 2 )12 - 8x - 4 = x + 28 - 8x = x + 2-8x - x = 2 - 8-9x = -6x = -6/-9X = 2/3
7x + 19 = -2x + 55Add 2x to both sides:9x + 19 = 55Subtract 19 from both sides:9x = 36Divide both sides by 9x = 4
