Simplify (6 - x - x2) ÷ (x2 - 4)
(3 + x) ÷ (x + 2)
(x - 3) ÷ (x - 2)
(x - 3) ÷ (x + 3)
(3 - x) ÷ (x + 2)
(3 - x) ÷ (x - 2)
Correct answer is A
(6 - x - x2) = ( 2 - x ) ( 3 + x ) divides ( x^2 - 4 ) = ( -2 - x ) ( 2 - x ) = ( 3 + x ) / ( x + 2)
If (x - a) is a factor of bx - ax + x2 - ab, what is the other factor?
(x + b)
(b - a)
(x - a)
(a + b)
(a - b)
Correct answer is A
