The quotient is x^2-5x+2
7x(3x3 - 2x2 + 5x + 1)
6x2 + 7x - 5 = (3x + 5)(2x - 1)
(3x+1)(x+2)
(x + 1)(2x + 5)
(2x + 1)(x + 3) are the factors.
1
7x + 8
20 + 7x
2y + 7x + y-1?
The three terms are 3x2, 7x and 1
7x/4 = 1/8 (7x/4) x (8) = (1/8) x (8) 14x = 1 x = 1/14
7x + 2
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
7x + 7 = 7(x + 1)
-8 + 7(6x) + 3 = -7x - 5 - 1-8 + 42x + 3 = -7x - 5 - 142x - 8 + 3 = -7x - 5 + (-1)42x - 5 = - 7x - 642x + 7x - 5 + 5 = - 7x + 7x - 6 + 549x = -149x/49 = -1/49x = -1/49
x2 + 7x + 6 = (x + 6) (x + 1)
7x(3x3 - 2x2 + 5x + 1)
