Answer:
9x^2-25
Step-by-step explanation:
You can solve this problem by using FOIL:
- FOIL (First, Outer, Inner, Last)
First: 3x*3x= 9x^2
Outer: 3x*-5= -15x
Inner: 3x*5 = 15x
Last: 5*-5= -25
Now add what we got together:
9x^2 -15x +15x -25
Answer: 9x^2 - 25
Note: Whenever when we see conjugates(coefficients of variables are same but real numbers are opposites) like these we can ignore the outer and inner of the foil process as they cancel out.
Hope this helps!
Given expression : 12.3 + 6 (n - 0.5)
Step 1 : substitute n = 3.7
12.3 + 6 (3.7 - 0.5)
Step 2 : Simplify the parenthesis
12.3 + 6 (3.2 )
Step 3 : Do the multiplication and open the parenthesis
12.3 + 19.2
Step 4 : Add the two number
12.3 + 19.2 = 31.5
So the answer of the given expression when n = 3.7 is 31.5
