delta math When the function f(x) is divided by 3x+7, the quotient is 3x^2+3x-2 and the remainder is −1. Find the function f(x)
vlabodo [156]

Answer:

x=√3

Step-by-step explanation:

Let's solve your equation step-by-step.

3x2+3x−2=3x+7

Step 1: Subtract 3x from both sides.

3x2+3x−2−3x=3x+7−3x

3x2−2=7

Step 2: Add 2 to both sides.

3x2−2+2=7+2

3x2=9

Step 3: Divide both sides by 3.

3x2

3

=

9

3

x2=3

Step 4: Take square root.

x=±√3

x=√3 or x=−√3

9-5 1/2 x - 3 (-2x+1)
Stells [14]
First, distribute the -3(-2x + 1). 
-3 x -2x = 6x      -3 x 1 = -3       -3(-2x + 1) = 6x - 3
Now we have: 
9 - 5 1/2x + 6x - 3 
Combine like terms. 
-5 1/2x + 6x = 1/2x         9 - 3 = 6
The two terms we are left with are 1/2x and 6. 
The simplified version of this expression is 1/2x + 6. 
Hope this helps!
