Solve for x x minus one by X - 2 + X - 3 by x minus 4 equal to 10 by 3
Answers
Answer:
=x-1/x-2+x-3/x-4=10/3
=(x^2-1-2x+x^2-3-4x)/x=10/3 {LCM}
=(2x^2-6x-4)/x=10/3
=6x^2-18x-12=10x {cross multiplication}
=6x^2-28x-12=0
=3x^2-14x-6=0
NOW, using quadratic formula,
D=b^2-4ac
=(-14) ^2-4(3)(-6)
= 196+72
=268
NOW, x=(-b+-√D)/2a
=(14+-√268)/2(3)
=(14+-2√67)/6
one time plus and one time minus,
=(14+2√67)/6 , (14-2√67)/6
= (7+√67)/3 , (7-√67)/3
:.x= (7+√67)/3, (7-√67)/3

Step-by-step explanation:

Values of x can be 0,2 and 4,but in the question it is given that x≠1,2,3
So,discard x=2
Value of x: 0 and 4
