In each of the following questions two equations are given. Solve these equations and give answer:

Correct option is A

I: x² + 3x – 28 = 0
x² – 4x + 7x – 28 = 0
x(x – 4) + 7(x – 4) = 0
(x – 4)(x + 7) = 0
x = 4, -7
II: y² - 12y + 35 = 0
y² - 7y – 5y + 35 = 0
y(y - 7) - 5(y - 7) = 0
(y - 7)(y - 5) = 0
y = 5, 7
