Answer:

Step-by-step explanation:
The given Equation is
.................(i)
Adding (
) on both sides of (i)
solving and cancelling out the terms will give
⇒
⇒
...................(ii)
Now we Know that
Applying this on equation (ii)

This will lead us to
Either 2x-3 =0 .......(iii) or 2x+3=0 ..........(iv)
Solving equation (iii) for value of x
2x - 3 =0
adding 3 on both sides
2x -3 +3 = 0+ 3
2x = 3
Cross multiplying gives

Solving equation (iv) for value of x
2x + 3 =0
adding -3 on both sides
2x -3 +3 = 0- 3
2x = -3
Cross multiplying gives

so
and 
Moving the decimal over by counting the 0's and moving over and if u move it past the the last number you add a decimal and put a 0 if there is not enough to numbers always move to the right
Answer:
the last one bottom right
Step-by-step explanation:
well, did it in my head, but the idea is to calculate it out
(x-8)*(x-8)=50
is just
x²-16x+64=50
to get the 64 down to just 5, we need to subtract 59, on both sides, leaving us with -9 on the righthand side
