Question

x^2=25 by factorisation method​

Answer 1

Answer : x =± 5

____________________________________

Explanation :

Given,

x² = 25

→ x² - 25 =

→ x² - 5² = 0

→ (x - 5)(x+5) = 0

Therefore :

x - 5 = 0 and x +5 = 0

→x = 5 , → x = -5

Answer 2

${x}^{2} = 25 \\ {x}^{2} - 25 = 0 \\ (x + 5)(x - 5) = 0$
either x-5 = 0 ,or x+5 =0
x= 5 x= - 5
