Solution:

Let us transpose -4 and 8x to the Left Hand Side. So we are left with 0 on the Right Hand Side.

Now, arrange the expression in standard form.

Now, split the mid term. Here, 3 × 4 = 12. So, we can split -8x into -2x and -6x.

Now, take 3x common from the first expression and 2 from the second.

When, two terms are equal to 0, then each term is equal to zero.

Hope you could understand.

If you have any query, feel free to ask.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
