Question

the distance between the points a(5 -3) and b(-2 3)
i will mark brilliant who write the right anwer first
​

Answer 1

Answer:

Let the two points be A(2,−3) and B(5,a)

∣A−B∣=5

⟹∣A−B∣

2

=25

⟹(2−5)

2

+(−3−a)

2

=25

⟹9+9+6a+a

2

=25

⟹a

2

+6a−7=0

⟹a

2

+7a−a−7=0

⟹(a+7)(a−1)=0

⟹a=−7 or a=1

But distance can't be negative

Hence a=1

Answer 2

Answer:

(a×5 -a×3) and (b×(-2) b×3)

5a-3a -2b×3b
