(x+1) x (3x-4) is the answer
vichka [17]3 years ago
3 0

Answer:

( x + 1 ) ( 3 x − 4 )

Step-by-step explanation:

3x^2− x − 4

Factor − 1 out of − x .

3 x^2 − ( x ) − 4

Rewrite − 1 as 3 plus − 4

3 x^2 + ( 3 − 4 ) x − 4

Apply the distributive property.

3 x^2 + 3 x − 4 x − 4

Group the first two terms and the last two terms.

( 3 x 2 + 3 x ) − 4 x − 4

Factor out the greatest common factor (GCF) from each group.

3 x ( x + 1 ) − 4 ( x + 1 )

Factor the polynomial by factoring out the greatest common factor, x + 1 .

( x + 1 ) ( 3 x − 4 )

Find f(g(x)) and g(f(x)).<br> f(x)=x²-2 and g(x)=√x+1
Archy [21]

Answer:

1. x - 1

2. \sqrt{x^2-1}

Step-by-step explanation:

f(g(x)) = \sqrt{x+1}^2 - 2\\ = x + 1 - 2\\= x - 1

g(f(x)) =\sqrt{x^2-2+1}\\ = \sqrt{x^2-1}
