What are the zeroes of f(x) = x2 - x-2?
ox=-2, 1
ox=2, -1
ox=-2, -1
o x = 2,1

Simplifying

0x =-2, 1

0 * x =-2.1

Apply rule () *a = 0

0=-2.1

Step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

[2, 2.5)

(2.5, 3]

step-by-step explanation:

i think its these two not sure [2, 2.5)

(2.5, 3]
