- Good morning class, today we will learn how to factor by grouping
- Say you have (5x^3-2x^2)-(25x-10).First, you need to find the GCF.GCF: x^2(5x-2)-5(5x-2).since the GCFs are x^2 and 5x , we'll combine them and get:(x^2-5)(5x-2)
- Good morning miss!
- Now ,I’m going to teach you how to factor the difference between two perfect squares
- no silly! perfect squares as in a number or variable that can be obtained by multiplying an integer by itself. for example, x^2 -16 can be split into (x-4)(x+4). don't forget to use both a negative and positive sign in each factor.
- squares? I don't see any squares let alone perfect squares.
- lastly we're going to take factoring the quadratic trinomial.
- no don't worry, it is actually quite simple. all you have to do is create two parentheses with an x in each. for the signs, the first sign will be the same as the first sign in the equation, and the second will be the sum of both. Lastly, you will figure out what two numbers if multiplied will give the c, and if added (or subtracted) will give the b. ex. x^2 + 4x + 3 will be (x+1)(x+3)
- this one looks very complicated!
