(i). x

2

-11x + 30 = 0​

Answer 1

Answer:

D= b^2-4ac

D=1>0

It has real and unequal root

x=6,5

Answer 2

${x}^{2} - 11x + 30 = 0 \\ by \: splitting \: the \: middle \: term \\ {x}^{2} - 6x - 5x + 30 = 0 \\ x(x - 6) - 5(x - 6) = 0 \\ (x - 5)(x - 6) = 0 \\ (x - 5) = 0 \: or \: (x - 6) = 0 \\ x = 5 \: or \: x = 6 \\ hope \: this \: helps \: you \: ...$
