(x - 4y)(x + y)
What is the reciprocal of a negative exponent when the exponent is a fraction?
The reciprocal of a^(-x/y) is 1/a^(x/y). The fact that the exponent is a fraction makes no difference.
How do you factor 3xy plus 3y squared?

What is is 3x times y?
3xy
Factor the polynomial 15x - 3xy plus 20 - 4y by grouping?
15x - 3xy = 3x(5 - y) 20 - 4y = 4(5 - y) 15x - 3xy + 20 - 4y = (3x + 4)(5 - y)
What is the answer of 2xy plus y-3xy?
-1
What is the coefficient of x in 3xy?
-3xy is a monomial where x and y are variables and -3 is the coefficient of the monomial.If we know the value of y, we have to substitute it for y, and we say that -3(y-value) is the coefficient of x.
What is the variable of -3xy?
It is x and y that are the unknown variables
What are M and Y if Y plus y plus y plus equals MY?

Is y equals 6 a linear function?
yes 3xy=6
What is 3xy minus 3xy?
3xy - 3xy = 0
3x y - 2y?
3xy-2y=0 3xy=2y y=2y (3x) y/2y=3x 1/2=3x multiply across by 2 1=6x 1/6=x therefore substituting x=1/6 into 3xy-2y; 3(1/6)y-2y=0 1/2y=2y y=2y/0.5 0.5 aka 1/2 y=1
What is the factor of 27x squared y squared - 36xy?
9xy(3xy - 4)
