Answer:
1. Perfect square trinomial on left sides is  .
.
2. The equation after applying the square root property of equality is  .
.
Step-by-step explanation:
The given equation is

It can be written as

Factor the perfect-square trinomial on the left side of the equation. 

 
        ![[\because (a+b)^2=a^2+2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%2Bb%29%5E2%3Da%5E2%2B2ab%2Bb%5E2%5D)
Therefore the required equation is

Taking square root both the sides.


Therefore the equation after applying the square root property of equality is  .

Answer:
1).
2).
Step-by-step explanation:
Here the given equation is 
We have to factor the perfect square trinomial on the left side of the equation
So left side of the equation is 
= 
 since [(a+b)²= a²+b²+2ab]
    since [(a+b)²= a²+b²+2ab]
Therefore the factorial form of the equation will be 

Now we have to solve the equation by applying square root property

Answer:
b + g = 25
b = g + 3
Step-by-step explanation:
Let b = number of boys.
Let g = number of girls.
"Mrs. Smith has a total of 25 kids in her class."
b + g = 25
"There are 3 more boys than there are girls."
b = g + 3
The system of equations is:
b + g = 25
b = g + 3
