Let a and b be the solutions to 7x^2 + x - 5 = -3x^2 - 9x - 4. Compute (a - 4)/(b - 4) + (b - 4)/(a - 4).

#1**+1 **

add -3x^2 to both sides

add 9x to both sides

add 4 to both sides

10x^2+10x-1 = 0

we can plug into the quadratic formula :

- we will get (-5+sqrt 35) / 10. or (-5-sqrt 35) / 10

then you can plug these value into the other expression we can get 412 / 199

i think you should work on getting to know the quadratice equation more + simplfying equations in general
