Question

Let f(x) = x2+x+1 and g(x) = 3x+2. Find 3f(x) - 2g(x)
Answer
3x2 - 3x -1
3x2 - 3x +1
3x2 + 3x -1
3x2 - 9x -7

Answer 1

3f(x) means 3 times f(x)
\[3(x^2+x+1)\]
2g(x) means 2 times g(x)
2(3x+2)
see if you can finish this

Answer 2

I got the last one

Answer 3

wait no the second

Answer 4

show me your work and I will double check it

Answer 5

3(x2+x+1)
3xsquared+3x+3-6x+4
3xsquared-3x+7

Answer 6

doesnt make since I got 7?

Answer 7

use the equation key to the lower left when you input questions

Answer 8

I will do it for you, give me a minute

Answer 9

\[3(x^2+x+1)-2(3x+2)\]
\[3x^2+3x+3-6x-4\]
\[3x^2-3x-1\]
