65 = 2x - 7x 65 = -5x 65/-5 = -5x/-5 -13 = x
2x plus 5x simplified is 7x.
If it's + 7x, the answer is (2x + 3)(5x - 4) If it's - 7x, the answer is (2x - 3)(5x + 4)
(21x3-23x2-76x-32)/(7x+4) = [3x2(7x4) -5x(7x+4)-8(7x+4)]/(7x+4)=3x2-5x-8
7x-5x=8 2x=8 x=4
5x-7x = -2
7x=2x-4 5x=-4 x=-4/5
35x2-36x-32 = (5x-8)(7x+4) when factored. 35*-32 = -1120 = -56*20 since -56+20 = -36 (35x - 56)(35x + 20) divide by 7 and 5 the coefficients of the two binomials (5x - 8)(7x + 4) or 35x2 - 56x + 20x - 32 = 7x(5x - 8) + 4(5x - 8) = (5x - 8)(7x + 4)
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
12x - 4 = 7x - 21 12x -7x = -21 + 4 5x = -17 x = -3.4
