First, you need to have j on it own. Since j is over 4-8, you times both sides of the inequality so the /4-8 is canceled. 

Your new inequality equation is j<4(4-8). Solve the bracket and then times the answer by 4.

~ j<4(-4)

~ j<-16

Answer:

-2. 46

- 9.54

Step-by-step explanation:

  • 2x²+12x-7=0
  • 2x²+12x+18= 25
  • 2*(x²+6x+9)=25
  • 2*(x+6)²= 5²
  • x+6= 5√2/2 ⇒ x= 5√2/2 -6 ≈ -2. 46
  • x+6= -5√2/2 ⇒ x= -5√2/2 -6 ≈ - 9.54
