Using the distance formula and the square root property, d(X;C) = r d(X;C)2 = r2, we see that this is precisely K def= f(x;y) j(x h)2 + (y k)2 = r2g (5.2) which gives the familiar equation for a circle. 2
Solve each equation by factoring. n 2 - 64 = 0.
There are three factoring formulas that will be used specifically for factoring binomials in this course. They are the difference of squares, the difference of cubes, and the sum of cubes. As …
Occasionally we can start by taking common factors out of every term in the sum. For example, Sometimes not all the terms in an expression have a common factor but you may still be able …
5.6 Special Factoring Formulas A. Perfect Square Factoring 1. Perfect Square Factoring Formulas: and 2. To use: if the first and last terms of a trinomial are squares , try writing a …
Solution 1: We solve by factoring. Using hint 1, we notice that 2 is a common factor, so we can pull it out. Hence, we have 2(x2 4x + 3). To determine the signs, we look at the equation 2(x2 …
Objective: Identify and factor special products including a difference of squares, perfect squares, and sum and difference of cubes. When factoring there are a few special products that, if we …

Find the common factor and take it out. Example 1: Factor 6 −4 . The common factor is 2x, thus we have 6 −4=2 (3 −2) Example 2: Factor 2 (−2 )+3(−2 ). We have a linear common factor (−2 …
Find and factor out the greatest common factor in each half separately. After factoring out the greatest common factor in each half, look to see if the remaining grouped terms are the same …
