Without an equality sign it is not an equation
They are: x and y and the expression can be simplified to 6xy
Calculate dx when xy3 + y = 3x.
3x2y
4xy2
It is a polynomial in x and y.
The GCF is 3x2y
xy(x^2 + 2x + y^2)
(x + y)3 + (x - y)3 = (x3 + 3x2y + 3xy2 + y3) + (x3 - 3x2y + 3xy2 - y3) = 2x3 + 6xy2 = 2x*(x2 + 3y2)
A polynomial term must have only a positive integer exponent for its variable(s). As we know a term is a number or a multiplication of a number and one or more variables associated by their exponents. Examples of terms: 2, -x, 3x2y, √5x5y-9z3w, 8x-7, 3/5, x2/3/y ect. Examples of polynomial terms: -10, -15z, √2x3y2z, 3x2y, ect.
7/100 is equal to 0.07.
7 does not equal negative 7.
