  1. Which expression is in simplified form for the given expression and states the correct variable restriction? U^2-4 over (u-6)(u-2)

Au + 2 over u - 6, U - 6
B1 over 2u + 12, u - 6
C1 over u - 3, u - 3
Du + 2 over u - 6, u2, u6

------------------------------------------

  1. Multiply. 5a3 . 2a over ab . 35

A2a3 over 7
Ba3 over 7b
C2a2 over 7
D2a3 over 7b

------------------------

  1. Multiply. (a-4)(a+3) . 2a3 over a2-4a . (a+3)(a-1)

A2 over a - 1
B2a2 over a-1
C2a over a + 1
D2a over a-1

----------------------------------

  1. Divide and simplify. 3x^3 over 4y divided x over 9

A27x over 4y^2
B27x over 4y^2
Cx^3 over 12
D27x^2 over 4

The first one should be A since you can factor u^2-4 into (u+2)(u-2)

Hi

(u²-4)/(u-6)(u-2)

= (u²-4)/(u²-8u+12)

= (u+2)(u-2)/(u-2)(u-6)

= u+2/u-6

The answer is A


5a³(2a)/ ab(35

= 10a^4/35ab

= 10a³/35b

= 2a³/7b

The answer is D
