If she knows the area is x feet squared, then you have to find the square root of the number, to find the side length. Hope that helps!
Answer: D x > -2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Do you remember the special case of factoring the difference of 2 squares ?
x² - 5 = (x + √5) (x - √5)
That will be zero if either factor is zero.
First factor:
x + √5 = 0
<u>x = -√5</u>
Second factor:
x - √5 = 0
<u>x = √5</u>
===================================
Another way to look at it is just to sit there and LOOK at it.
<u>x² - 5 = 0</u>
x² = 5
This is true if x = + or - √5 .
