-11x + 13
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
2x2-9x+4 = (2x-1)(x-4) when factored
Assuming the equation is exactly as you described in words, it would be expressed algebraically as 9X+(6-4X-2X)+(1-15) 9X+(6-4X-2X)+(1-15) First, Combine all like terms inside the parenthesis 9X+(6-6X)+(-14) Next, clear the parenthesis. This is done by distributing the "1" coefficient implied by the parenthesis over the entire parenthesized term. 9X+1(6-6X)+1(-14) 9X+6-6X-14 Combine like terms again to get your answer! =3X-8
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
(2x + 1)(x + 4)
Assuming it's a plus sign, that factors to (2x + 1)(x + 4)
[9x-5x+1] + [16x-2x-9] [4x+1] + [14x-9] [18x2+8]
5x + 3 - 4 + 4x = 9x -1
(11x - 1)(2x + 1)
If you mean: 2x^2 +9x +7 then it is (2x+7)(x+1) when factored
9x + 7 - 2x = 14 Combine like terms: 7x + 7 = 14 Subtract 7 from both sides: 7x = 7 Divide both sides by 7: x = 1
6x2 + 11x + 3 = 6x2 + 9x + 2x + 3 = 3x(2x + 3) + 1(2x + 3) = (2x + 3)(3x + 1)
