Short Answer

Expert verified

The solution ism=233.

Step by step solution

01

Step 1. Given Information  

We are given the quadratic equation 3m+2-5=0and we need to solve it.

02

Step 2. Finding the solution 

Isolating the radical on one side of the equation:

3m+2-5=0鈬�3m+2-5+5=5鈬�3m+2=5

Squaring both sides of the equation, we get:

3m+22=52鈬�3m+2=25鈬�3m=25-2鈬�3m=23鈬�m=233

03

Step 3. Checking the answer 

m=233,3233+2-5=0鈬�23+2-5=0鈬�25-5=0鈬�5-5=0鈬�0=0
