Answer:
14/10 or 1 2/5
Step-by-step explanation:
Hey there!
In order to simplify this expression, we need to add the numerators and not the denominator since they are the same
14/10 is what you will get or this is also 1 2/5
STEP-BY-STEP SOLUTION:
= a^3 - 4a^2 + 12 - 3a
= a^2 ( a - 4 ) + 3 ( 4 - a )
= a^2 ( a - 4 ) - 3 ( a - 4 )
= ( a - 4 ) ( a^2 - 3 )
