Can someone help me simplify 4(3x+2)−2
I know some steps to it but I keep getting confused
4(3x+2)−2
12x + 8 - 2
12x + 6
Repost the other question in another post. There will be several math tutors on this evening.
Also another question but I want to solve the first one first.
Factor the expression completely. (1 point)
20b−16
wait so do you add 12x and 6? So would it be 18x?
Also where it the 8 from? Sorry, I just want to understand it
No. You can't add 18x and 6. We don't know what x is.
4 * 2 = 8
Sorry -- but I don't know how to factor that expression.
wait didnt you use the 4 for 4x3? Sorry i am confused
If you don't mind showing the steps broken down I would like that, unless you have no time. Also, do you know any other tutors that could help me with the other question?
Of course! Simplifying expressions involving parentheses can indeed be confusing at times. Let's break down the steps together to simplify the expression 4(3x+2)−2:
Step 1: Apply the distributive property
When you have a number outside parentheses multiplied by a binomial, you need to distribute or multiply that number by each term inside the parentheses. In this case, we need to multiply 4 by both 3x and 2:
4(3x+2) = 4 * 3x + 4 * 2
Simplifying further, we get:
12x + 8
Step 2: Subtract 2
After applying the distributive property in step 1, we have the expression 12x + 8. The next step is to subtract 2 from this expression:
12x + 8 - 2
Simplifying further, we get:
12x + 6
So, the simplified form of 4(3x+2)−2 is 12x + 6.
