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 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)
