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
When the value of x is 3, evaluate;
Substitute for the value of x into the parenthesis;
ANSWER:
The expression equals 40 (when x = 3)
