Answer: =x4+3x3+2x2−4
Step-by-step explanation:
(x2+3x+2)(x2)−4
Distribute:
=(x2)(x2)+(3x)(x2)+(2)(x2)+−4
=x4+3x3+2x2+−4
7 is 1/10 of 70 because 7 can go into 70 10 times
Answer:
x = 2
Step-by-step explanation:
First, let's write out our equation:

I want to isolate x on one side, so first, I'll add 4 to both sides to remove the -4 from next to 2x:

Notice that I combined like terms with the -4 and 4 (to get 0) and the 6 and 4 on the right side (to get 10). Next, I'll add 3x to both sides:

And then I'll add like terms:

Now, all we have to do is divide both sides by 5:

And there's our answer. Hopefully that's helpful! :)
