F(x) = 2x + 6, g(x) = 4x2 Find (f + g)(x).

1 answer:

5 0

(f+g)(x) is simply saying add these two problems together.

(2x+6) + (4x^2)

Parenthesis are now useless, as there is only addition.

2x + 6 + 4x^2

Reorder, cause it's pretty and familiar

4x^2 + 2x + 6

We could further simplify

2(2x^2 + x + 3)

How can you subtract fractions with unlike denominators?

Rama09 [41]

Answer:

No, You can't. You have to make their denominators equal!

$-\frac{7}{10}$

Step-by-step explanation:

So first, you make their denominators equal!

$\frac{1*2}{5*2} =\frac{2}{10}=\frac{1}{5}$

Multiplying both the numerator and denominator with the same number results in the same fraction, just un-simplified

So, we input it!

$\frac{2}{10} -\frac{9}{10} = -\frac{7}{10}$

There you go!

Hope you get better at math!(gets wayyyyyyyyyyy...y more complicated later)

Hope this helps!

See Ya!
