Answer:
x = ± 5
Explanation:
Given
x² = 625
We require to find the number that when squared results in 625
To find this value take the square root of both sides
= ± ← note plus or minus
x = ± 25
since 25 × 25 = 625 and - 5 × - 5 = 625
x1= -25
x2= 25
square root of both sides of the equation and remember to use both positive and negative roots
