Answer: D. -1(3x+2)(x+1)
Step-by-step explanation: First, use the F.O.I.L. method (First, Outer, Inner, Last). Then combine all your like terms. After, multiply the whole outcome by negative one. So, 3 turns into -3
; 5x turns into -5x; and 2 is -2. BOOM! you got the exact right answer.
Answer:
The simplified form is .
is the excluded value for the given expression.
Step-by-step explanation:
Given:
The expression given is:
Let us simplify the numerator and denominator separately.
The numerator is given as
2 is a common factor in all the three terms. So, we factor it out. This gives,
Now,
Therefore, the numerator becomes
The denominator is given as:
Factoring out 3, we get
Now, is of the form
So,
Therefore, the denominator becomes
Now, the given expression is simplified to:
There is in the numerator and denominator. We can cancel them only if
as for
, the given expression is undefined.
Now, cancelling the like terms considering , we get:
Therefore, the simplified form is
The simplification is true only if . So,
is the excluded value for the given expression.
