Soil order characterized by low (< 35%) base saturation

I. x² - 4x – 21 = 0

II. y² + 12y + 20 = 0

The following question contains two equations as I and II.You have to solve both equations and determine the relationship between them.

I. 6 y² + 11 y – 7= 0

II. 21 x² + 5 x – 6 = 0

Find the remainder when x⁵ − 3x⁴ + 4x³ − 6x² + 8x − 3 is divided by (x − 2).

I. y/16 = 4/y 

II. x³ = (2 ÷ 50) × (2500 ÷ 50) × 4² × (192 ÷ 12)

I). p² - 20p + 51 = 0,

II). 2q² - 7q + 6 = 0

I.8^(x+3)+ 8^(-x)=72 

II. 5^(y+5)+ 5^(-x)=150 

(i) x² – 3x – 40 = 0

(ii) y² + 11y + 30 = 0

I. 2x² - 9 x + 9 = 0

II. 2y² - 7 y + 3 = 0
