Factoring trinomials and difference of squares. I need to understand the steps.

Factoring the term we get

Step-by-step explanation:

We need to solve the polynomial:

First we see that 3 is common term, so taking 3 as common

We know that 25 = 5x5 = 5²

So, replacing 25 with 5²

We know that,

Applying this in our equation:

So, factoring the term we get

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)
