Could you please provide the equation and the rest of the question?
A line with undefined slope has an equation x=a.
So, for a line that passes through the point (x,y) = (-3,5) ,
has the equation x= - 3.
Correct answer is 0.2
0.2 * 0.2 is 0.04
then 0.04 * 0.2 = 0.008
The missing number is the square-root of the constant term on the left-hand-side, which equals sqrt(1/16)=1/sqrt(16)=1/4.
Check:
(x+1/4)^2=x^2+2*(1/4)x+(1/4)^2=x^2+x/2+1/16. ok
Answer: x= 1/4
