HCF of 10(x²-1) and 15(X+1)⁴(2x+3)
Answers
Answer:
Let ;-
A = ( 1 , -1 , 3)
B = ( 2 , -4 , 5)
C = ( 5 , -13, 11)
If , all these points lie on the straight lines than ;-
=> AC = AB + BC
=> AB = √( 2-1 )² + ( -4 + 1)² +( 5-3 )²
=> AB = √ 1 + 9 + 4
=> AB = √ 14
=> AB = 2√5
=> BC = √ ( 5 - 2 )² + ( - 13 + 4 )² + ( 11 - 5 )²
=> BC = √ 9 + 81 + 36 = 3 √ 14
=> AC = √ ( 5 - 1 )² + ( - 13 + 1 )² + ( 11 - 3 )²
=> AC = √ 16 + 144 + 64
=> AC = 4 √ 14
=> AB + BC = AC
=> L. H. S = √ 14 + 3√ 14
=> L. H. S. = 4 √ 14 = AC
=> L. H. S. = R. H. S.
Therefore,
The given points are in a Straight line.
