(x + 4)(3x - 5)
3x2-7x+4 = (3x-4)(x-1) when factored
(3x + 5)(x - 4)
3x2 - 7x - 20 = (3x + 5)(x - 4)
(3x - 5)(x + 4)
(3x - 4)(x - 1)
The three terms are 3x2, 7x and 1
3x2-7x-20 = (3x+5)(x-4) when factored
(21x3-23x2-76x-32)/(7x+4) = [3x2(7x4) -5x(7x+4)-8(7x+4)]/(7x+4)=3x2-5x-8
(3x+1)(x+2)
3x2+7-6 = (3x-2)(x+3) when factored
-7
The sum 6 (3x^2) + 8x -3 plus 3 (3x^2) - 7x + 2 = 27 x^2 + x -1
