For which equation does it make the most sense to solve by using the square root property?

x^2+4x=−3

x² + 2x + 1 = 0

4x^2−5=20

2x^2+3x=−3

The answer is (c)

Step-by-step explanation:  We are given four quadratic equations out ofehich we are to select the one which can be best solved by the square root property.

We can see that the equations invove the single power of 'x', so hey can be solved by completing the square method.

But the equation does not involve x, only x², so it makesthe most sense to solve this equation by square root method. The solution is as follows:

Thus, the correct option is (c)

345

step-by-step explanation:

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)
