What is value of an expression?
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.
What are examples of exponents?
An exponent is a small, raised number (or symbol, or expression), as in: 53 ab 2xy 105+5 etc.
Factor the trinomial x2 2x - 15?
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)
What are the factors of the expression g squared minus 14 g plus 45?
It is: (g-5)(g-9)
Is this a binomial 2xy?
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.

How do you factor expression?
2(10XY) 5(2XY) 4(5XY) 22(5XY) and so on, though not very interesting factoring

2xy x equals 5 y equals 3?
2xy substitute 3 for y and 5 for x 2(5)(3) = 30
In the expression 3.2x5 the numbers 3.2 and 5 are?
factors
What are the like terms of 3xy 5-2xy 10?
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.
Factor 2xy -10x plus 3y -15?
2xy - 10x + 3y -15 = 2x(y - 5) + 3(y - 5) =(y - 5)(2x + 3)
Factor the trinomial x2 2x - 15?
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)
What are the factors of this expression 5b 15?
5b + 15 = 5(b + 3)
What multiplication expression equals 225?
As a product of its prime factors: 3*3*5*5 = 225
What does prime factorization and algebraic expression means?
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.
Do 5 plus x and x plus 5 represent the same expression?
the order of the factors does not alter the result
