When you have an algebraic expression with variables in it, you need to know the the value of each variable. The value of the expression is found by replacing the variables with their values and simplifying. For example, evaluate 2xy-3x if x=5 and y=-1. 2xy-3x = 2*5*(-1) -3*5 = -10-15 = -25.
An exponent is a small, raised number (or symbol, or expression), as in: 53 ab 2xy 105+5 etc.
If the expression is, x2 + 2x - 15 this has factors of (x + 5)(x - 3). If the expression is, x2 - 2x - 15 then the factors are (x - 5)(x + 3)
It is: (g-5)(g-9)
No, it's not a binomial. (x + 5) is an example of a binomial. A binomial has more than one term. Just look at the word binomial and you will know why. Bi means two.2xy is a monomial. Mono means one.

2(10XY) 5(2XY) 4(5XY) 22(5XY) and so on, though not very interesting factoring

2xy substitute 3 for y and 5 for x 2(5)(3) = 30
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.
2xy - 10x + 3y -15 = 2x(y - 5) + 3(y - 5) =(y - 5)(2x + 3)
factors
If the expression is, x2 + 2x - 15 this has factors of (x + 5)(x - 3). If the expression is, x2 - 2x - 15 then the factors are (x - 5)(x + 3)
5b + 15 = 5(b + 3)
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this.Example: 210210 Divide by two.105,2 Divide by three.35,3,2 Divide by five.7,5,3,2 Stop. All the factors are prime.2 x 3 x 5 x 7 = 210That's the prime factorization of 210.In mathematics, an algebraic expression is an expression built up from constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number). For example, 3x2 - 2xy + c is an algebraic expression.
As a product of its prime factors: 3*3*5*5 = 225
the order of the factors does not alter the result
