2x + 4x will always be larger or equal to 0.
if x= 0 than it will be equal to 0.
Does this help at all?
Would assume it to be 36x² - 25 = 0
<span>36x² - 25 = 0
</span>
<span>(6x)² - 5</span>²<span> = 0</span>
(6x + 5)(6x - 5) = 0 By difference of two squares.
6x + 5 = 0 or 6x - 5 = 0
6x = -5 6x = 5
x = -5/6 x = 5/6
x = +5/6 or - 5/6
0.96 is the answer to this question
On #1, x= 62°
Because you would divide 124° by 2
On #2, x=139°
Because since it is the center point it is the same
Hope this helped :)
