Which strategy is the most appropriate to solve : x^2 - 8x = 242 ?

a. completing the square
b. zero product property
c. square root property

The appropriate strategy is (A). Completing the square.

Step-by-step explanation:  The given quadratic equation is

Since the constant term is not equal to zero, so Zero product property is no appropriate to solve the equation.

From equation (i), we have

The left hand side of the above equation is not a perfect square, so the square root property is also not appropriate.

Completing the square strategy is appropriate to solve the equation (i).

The solution using this strategy is as follows:

In this way, we can solve the equation by Completing the square strategy.

Thus, (A) is the correct option.

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
