Answer:
x = 5±2√7
Step-by-step explanation:
This quadratic cannot be factorised via the factorisation method, so we use the quadratic formula :
x =
or x =
(The reason I did 2 equations is because brainliest does not allow me to do the ± in the equation insert thing )
x =
or x =
x =
or x= 
x =
or x = 
x =
or x =
Hope this helped and brainliest please
Answer:
x = 
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
128=12(8+x)
128=(12)(8)+(12)(x)(Distribute)
128=96+12x
128=12x+96
Step 2: Flip the equation.
12x+96=128
Step 3: Subtract 96 from both sides.
12x+96−96=128−96
12x=32
Step 4: Divide both sides by 12.

x=8/3
If i were going by guesses i’d say y=x. sorry if i’m wrong.
