Question

X2-3√5x+10=0 factorise this by factorisation method​

Answer 1

Answer:

(x-√5) (x-2√5)

Step-by-step explanation:

x^2- 3√5x+ 10= 0

x^2- 2√5x- √5x+ 10= 0

x(x-2√5)- √5(x-2√5)= 0

[Since, 10 can be written as 2√5×√5]

(x-√5) (x-2√5)

Answer 2

Step-by-step explanation:

x²-3√5x+10=0

x²-2√5x-√5x+10=0

x(x-2√5)-√5(x-2√5)=10

(x-2√5)(x-√5)=0

Hence the factors are (x-2√5) and (x-√5)
