Step 1: Make equation equal to Zero
3x^2 = 4x + 2
3x^2 - 4x - 2
Step 2: use equation
a= 3 b = -4 c= -2
after plugging in answer should be
(2 + or - sqrt 10) / 3
Answer:
Step-by-step explanation:
This is a super question and it is an excellent exercise for you. When I was teaching, once every term, I would ask my physics class to explain acceleration to a 7 year old. The stats favored the older women (mothers) who took the class. Almost none of the guys could do it. Here's why.
- The sentences had to be very short. They were barely 6 or 7 words long. They were complete sentences.
- The examples used had to be very simple. The secret to those mother's answers was they invariably picked something like a stop sign. They all knew that and they always got it right for those reasons.
You are trying to teach a seven or eight year old. Believe it or not, the first thing you have to do is check and see if they know their facts. Can they do 7+8 or 9+ 6 without hesitancy. If they can do those facts do they know the multiplication facts. 4 * 5 etc. They must know those things cold, or you are wasting your time. Don't ask me why. But you can't go on without those 2 fact types solid.
I take it you are trying to do word problems. The best thing you can do is teach them to read.
A man has a dime and a nickel and a penny. How much money does he have? Us a marker to underline the key statement.
a dime,
a nickel
a penny should be underlined. Don't ask for an answer - yet.

Keep doing this problem over and over. You are not trying to get an answer. You are trying to get them to understand how to read a question
A person has just less than 4 quarters just less than 5 dimes and just less than 4 nickels. How many coins does he have. That's an important question because the grade three-er is going to have to know what less means.
That should get you started.
Answer:
7g+5 I'm pretty sure
Step-by-step explanation:
6g+g=7g 9-4=5
so it's 7g+5 simplified
Answer:
B. 279
Step-by-step explanation:
Answer:
(2y - 5) (3y^2 - 4)
Step-by-step explanation:
Group and factor by using the Greatest Common Factor (GCF).
6y^3 - 15y^2 - 8y + 20
Simply multiply the terms inside the first pair of parenthesis, by the terms in the second pair of parenthesis.
2y x 3y^2 = 6y^3
2y x (-4) = 8y
-5 x 3y^2 = 15y^2
-5 x (-4) = 20
6y^3 - 8y -15y^2 + 20
Now, simply simplify the problem!
(2y - 5) (3y^2 - 4)
