(2y + 1) + (y^2 + 1) = 2y + 1 + y^2 + 1 = y^2 + 2y + 2
If that's -18y2, the answer is (3x - 2y)(x + 9y)
3y squared - 2y = 1
(5x - 2y)(5x + 2y)
(3x-2y)2=
42+4y -12 = 13y -12 -2y 4y -13y+2y = 12 -12 -42 -7y = -42 y = 6
9y cubed plus 2y squared
2y + 1
2y^2+5y+2=(2y+1)(y+2)
6xyz(3x + 2y + z)
(2y - 5)(y - 2)
(2y + 5)(y - 9)
(2y + 1) + (y^2 + 1) = 2y + 1 + y^2 + 1 = y^2 + 2y + 2
It is 2y + 22 = 2(y + 11)
It is like saying, "How much is 8 yams plus 2 yams plus 3 yams?" Add the numbers: 8+2+3 = 13. The answer is the number of yams. 8y+2y+3y = (8+2+3)y = 13y.
If that's -18y2, the answer is (3x - 2y)(x + 9y)
3y squared - 2y = 1
