It means: 2 times y
(root of )
There is no one rule to algebra. There are different rules that apply to different functions.
It is: 7y+2
2x^2 - 1
The product of a number and 20
4x-2y+3x+2y When simplified: 7x
2y squared * y cubed= 2y^5 (2y to the fifth power)
-2y+y = -y
-6x = 2y - 120 -2y -2y -2y - 6x = -120 +6x +6x -2y = 6x - 120 -2y/-2 = 6x/-2 - 120/-2 y = -3x + 60
Yes. It is like having a-b, which is a+(-b), which is -b+a, so 3-2y = 3+(-2y) = -2y+3
2y+8y2 can be factored to 2y(1+4y)
2y-10y
