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

x2=3

Step 4: Take square root.

x=±√3

x=√3 or x=−√3
