Environmental degradation is a big problem of modern

I. 6 y² + 11 y – 7= 0

II. 21 x² + 5 x – 6 = 0

I. x²  – 44x + 468 = 0

II. y²  – 30y + 216 = 0

I. 2y² - 15y + 18 = 0

II. 2x² + 9x - 18 = 0

Solve: x² − 7x + 12 = 0

Solve the quadratic equations and determine the relation between x and y:

Equation 1: x² - 40x + 375 = 0

Equation 2: y² - 36y + 324 = 0

I: 2x² - 8x + 6 = 0

II: 3y² - 12y + 9 = 0

If x^2 - 7x + k = 0 has roots that are equal, what is the value of k?

I. 4x² -  15x + 9 = 0

II. 20y² -  23y + 6 = 0

I. 2x² – 5x - 12 = 0

II. y² – 11y + 30 = 0

Equation 1: x² - 220x + 12100 = 0

Equation 2: y² - 210y + 11025 = 0
