WebGreatest common factor (GCF) of 5 and 8 is 1. GCF (5,8) = 1 We will now calculate the prime factors of 5 and 8, than find the greatest common factor (greatest common … WebExample: Factor 4x 2 − 9. Hmmm... there don't seem to be any common factors. But knowing the Special Binomial Products gives us a clue called the "difference of squares":. Because 4x 2 is (2x) 2, and 9 is (3) 2,. So we have: 4x 2 − 9 = (2x) 2 − (3) 2. And that can be produced by the difference of squares formula:

WebNow let us know how to calculate the prime factors of 16. The first step is to divide the number 16 with the smallest prime number, say 2. 16 ÷ 2 = 8. Again divide 8 by 2 and the process goes on. 8 ÷ 2 = 4. 4 ÷ 2 = 2. 2 ÷ 2 = … WebApplying rule: A product is zero when some of its factor is zero. Either one of the 3 must be 0. I. 2x=0 -> x=0. II. x+1=0 -> x=-1. III. 2x-3=0 -> x=3/2. So you just solved a cubic equation without using any higher college level math. Not working always but certainly an useful skill to learn in high school math. dreamstime very relaxed woman
