Question

The equation: x2=25
will have how many solutions for x ?(1 point)

Two solutions: x = 252
and x = - 252
since the inverse operation is division and x 2
equations always have 2 solutions

One solution: x = 5 since 5 2
= 25

One solution: x = 252
since the inverse operation is to divide

Two solutions: x = 5 and x = -5 since 5 2
= 25 and also (-5) 2
= 25 and x 2
equations always have 2 solutions

Answer 1

x^2 = 25 has two solutions: x = ±√25 = ±5.

You cannot "divide by 2" to undo a square — the inverse operation is taking the square root, which gives both +5 and −5 because both (5)^2 and (−5)^2 equal 25.
