Answer:

Step-by-step explanation:
When two or more quantities have the same exponents, their bases can be multiplied together.
Naw bruv i’m doing the same problems rn and i’m struggling gl tho
We must graph y=x^3-9x^2+11x+21. Please, see the attached file.
Then we see were the graph cuts the x-axis, and these values of x are the real solutions of the given equation:
The real solutions of the given equation are:x = -1, 3, and 7
It is necessary to include the term one then you will have the plus three
<span>6x+7=6
Subtract both sides by 7
</span>6x+7-7=6-7
6x=-1
Divide both sides by 6 to isolate x
6x/6=-1/6
x=-1/6
