3xy2z
5x + 8xy + 10x + 3xy = 15x + 11xycombine like terms (the x's and the xy's)
It is the same as: 12y^2 -3xy
yes 3xy=6
2x^2+3xy-4y2(4)+3(2)(-4)-(4)(-4)8-24+16=0
3xy - 3xy = 0
Whenever you see a variable (letter) without any exponent, it's exponent is 1.
A number, a variable, or a product of a number and one or more variables. Ex: 3xy,x, and 14 are monomials.
3xy
18x3y5 + 9xy3 - 3xy = 3xy(6x2y4 + 3y2 - 1)
3xy-4x + 15y-20 Sol: As there are no number are same. So -4x-3xy +15y-20 -------------------- -4x-3xy+15y-20
1,3,x,y,3x,3y,xy,3xy
3xy
3xy and 2xy. You can see that 3xy and 2xy have something in common with each other. They both have xy and the end of them. Hope this helped.
A term is a constant number, a variable, or a variable with a coefficient. Terms are separated from each other by addition or subtraction signs. For example, -7x is a term. 3xy is a term. 4b+m is two terms.
3xy + 3y2 = 3y (x + y)
