Differences of Squares (and other even powers) ?
A square monomial is a monomial which is the square of another monomial. Here are some examples:25 is the square of 5x2 is the square of xx4y6 is the square of x2y325x4y6 is the square of 5x2y3
How do you know if a monomial is a square? It's easy. It's a square if
1. the coefficient is a perfect square (which, by the way, means it can't be negative) and 2. all the exponents on the variables are even.
Remember that the word difference means subtraction. So here's an example of a difference of squares: 25 - 4x2.(Notice that 25 is a perfect square, and so is 4x2.)Factoring a difference of squares is easy.
Step 1: Rewrite the two terms as squares of something.25 - 4x2= 52 - (2x)2 Step 2: Apply the rule a2 - b2 = (a -b )(a + b).
= (5 -2x)(5 + 2x)
Example : Back into the complex root section we complete the claim that y 1 (t ) = e l t cos(µt) and y 2 (t) = e l t sin(µt) Those were a basic set of soluti
Determine the equation of the plane that consists of the points P = (1, -2, 0), Q = (3, 1, 4) and R = (0, -1, 2). Solution To write down the equation of plane there is a re
Hi, I don''t know how to solve 2(5x+3)

The next kind of problem seems as the population problem. Back in the first order modeling section we looked at several population problems. In such problems we noticed a single po
Factoring Out a Common Monomial Factor? Say you have a polynomial, like 3x 4 y - 9x 3 y + 12x 2 y2 z and you want to factor it. Your first step is always to look for t
Give the example of Exponents? When a number is multiplied several times, it is easier to write it as an exponent. For example, four multiplied to itself three times, is writte
Example Factorize x 2 - 4x + 4. If we substitute x = 1, the value of the expression will be (1) 2 - 4(1) + 4 = 1 If we substitute x = -1, the value o
