What is the purpose of conditional formatting in

I.  2^(x+2)+ 2^(-x)=5

II.  (1/(y+1)+ 1/(y+5))=(1/(y+2)+  1/(y+4))

I. x − √2401 = 0

II. y² − 2401 = 0

I. 6 y² + 11 y – 7= 0

II. 21 x² + 5 x – 6 = 0

I. 22x² - 97x + 105 = 0

II. 35y² - 61y + 24 = 0

I. p² - 53p + 672 = 0

II. q² - 27q + 126  = 0

I. 17x² - 26x – 16 = 0

II. 17y²- 26y + 9 = 0

I. x² – 39x + 360 = 0

II. y² – 36y + 315 = 0

If the roots of the quadratic equation 5x² + 4x + 6 = 0 are α and β, then what is the value of [(1/α) + (1/β)]?

(i) 2x² – 12x + 16 = 0

(ii) 2y² – 20y + 48 = 0

l).  2p² + 12p + 18 = 0 

ll).  3q² + 13q + 12 = 0
