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.


How do you factor expression?

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


What are examples of exponents?

An exponent is a small, raised number (or symbol, or expression), as in: 53 ab 2xy 105+5 etc.


2xy x equals 5 y equals 3?

2xy substitute 3 for y and 5 for x 2(5)(3) = 30


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 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)

5b + 15 = 5(b + 3)


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.


What multiplication expression equals 225?

As a product of its prime factors: 3*3*5*5 = 225


Do 5 plus x and x plus 5 represent the same expression?

How many factors are in 9x4?

9x4 = 32*x4 has (2+1)*(4+1) = 3*5 = 15 different factors. When an expression is written out as the product of its prime factors in index form, the number of factors can be calculated as the product of each index increased by one.
