Question

Solve by Factorisation Method a²-25=0​

Answer 1

Answer:

${a }^{2} - 25 = 0 \\ \\ {a}^{2} = 25 \\ \\ a = \sqrt{25} \\ \\ a = + 5 \: and \: - 5$

Answer 2

Answer:

hope this helps u

Step-by-step explanation:

a²-25 = 0

25 = 5*5 = 5²

so

a²-5²=0

[a²-b²]= ( a+b)(a-b)

[a²-5²] =  ( a+5)(a-5)
