Question

find the root (a)2x^-7x +3 (b)1/x+4-1/x-7=11/30​

Answer 1

Answer:

2x²-7x+3=0

or, 2x² -6x -x +3=0

or, 2x(x+3) -(x-3)=0

or, (x+3)(2x-1)=0

or, x= -3 , 1/2

1/(x +4 )- 1/(x-7) =11/30

or, 30 × (x-7-x-4) =11(x+4)(x-7)

or, -330= 11x²-33x-308

or, 11x²-33x+22=0

or, x²-3x+2=0

or, (x-2)(x-1)=0

or, x= 2 , 1
