Question

4/x =3x-7/5 using quadratic formula​

Answer 1

Answer:

x=7+√1249/30 or x=7-√1249/30

Step-by step explanation:

Directly using -b+-√b^2-4ac/2a we can find both the zeroes.

Answer 2

Answer:

4/x= 3x-7/5

by cross multiplication

4 × 5 = x × (3x-7)

20= 3x²-7x

3x²-7x-20=0

by using Quadratic formula

x= -b± √b²-4ac/2a

here a=3, b=-7 and c=-20

by putting values in formula sa

x=-(-7) ± √(-7)²-4(3)(-20)/2(3)

x=7 ± √49+240/6

x=7 ± √289/6

x=7 ± 17/6

x=7 + 17/6  and x=7 - 17/6

x=59/6 and 25/6

solution set {59/6, 25/6}
