So

remember

translates to

basically, the power that a must be raised to to obtain c is b
so

translates to
19. (X+5)-3
20. 2a
21.3b
22. 5y-5
23. 1/2n-15
Answer:
see below
Step-by-step explanation:
The first step is to read the problem
Then you need to make a plan
Implement the plan
Then evaluate the answer to see if it makes sense
Answer:
c. a: 4
b: 12
c: 9
4x² +12x+9=0
(2x+3)(2x+3)= 0
(2x+3)²=0 {square root both sides}
2x+3=0
2x=-3
x= -3/2
