How do you factor 4a plus 8b 16c?
With the factor 4a plus 8b 16c you can find the answer and check it mentally. You would first have to find he product of all the numbers to find the value of the letter A.
How do you solve 5x squared minus 12x plus 10 equals x squared plus 10x?
Subtract the stuff on the right from the stuff on the left. Get 4x2 - 22x + 10 = 0 Factor that. 2(x - 5)(2x - 1) = 0 x = 5, 0.5 Check it. 125 - 60 + 10 = 25 + 50 (75 = 75) Check. 1.25 - 6 + 10 = 0.25 + 5 (5.25 = 5.25) Check.
How do you factor trinomials?
you do 2 sets of parenthesis and check it. for example: w2(w squared)-7w-8 (w+1) (w-8) *if you add 1w and -8w you will get -7w, which is what they want you to get. and w & w multiply to get w2(w squared), which is also what the factoring wants. another example: 3w2 (3w squared)+2-8 (3w-4) (w+2) *same thing applies with 3w x w = 3w2, and -4 +2=2, which is the answer. use this theory in all of them, unless there is a greatest common factor (GCF).
