Lets change x²=y, so we have equation y²+6y-7=(y-1)(y+7)
make change back so (y-1)(y+7)= (x²-1)(x²+7)=(x²-1²)(x²+7)=(x+1)(x-1)(x²+7)

Answer:

Step-by-step explanation:

Let's find (f-g)(x)

$3x^{2} + 1 - (1-x)\\3x^{2} + 1 -1 + x\\3x^{2} + x$

Now let's plug in x=2, so to find (f-g)(2)

$3(2)^{2} + 2\\12 + 2 = 14$
