It is mandatory (required) to use " ^ " for exponentiation:
(3x – 5)^2 = 4
Taking the square root of both sides, we get
3x - 5 = ±2, or
3x = 5 ±2, or
(a) 3x = 7 => x = 7/3, and
(b) 3x = 3, or x = 1
I believe it's 2a + 2c So sory if it's wrong!
Answer:

Step-by-step explanation:
It helps me to convert the fractions into decimals, so 11/15=.73 and -5 1/2= -5.5.
