Solve x2 + 1 = 0. Question 3 options: A) x = ±0.5 B) No real solution C) x = 0 D) x = ±1

B

Step-by-step explanation:

x^2 + 1 = 0

subtract both sides by one.

x^2 + 1 - 1 = 0 - 1

x^2 = -1

put both sides under square root to find the value of x

sqrt (x^2) = sqrt(-1)

we know that a number inside a square root must always be greater or equal to 0. thus, we don't have a real solution.

✨Extra - It says "no REAL solution" because imaginary solutions exist which are the set of complex numbers in an imaginary coordinate system.

B

Step-by-step explanation:

x² + 1 = 0 ( subtract 1 from both sides )

x² = - 1

no real number when squared gives a negative value.

Thus the equation has no real solution

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
