Answer:
B. -1
Step-by-step explanation:
x^3-4x^2+2x+10=x^2-5x-3
We know it has 3 roots since it is a 3rd degree polynomial.
Two of the roots are (3+2i) and (3-2i)
Subtract x^2-5x-3 from both sides
x^3-4x^2+2x+10-(x^2-5x-3)=x^2-5x-3 -(x^2-5x-3)
Distribute the minus sign
x^3-4x^2+2x+10-x^2+5x+3=x^2-5x-3 -x^2+5x+3
x^3 -5x^2+7x +13 =0
Graphing this equation , we see that it crosses the x axis at x=-1
That covers the three roots, 1 real and two complex

Step-by-step explanation:
Answer:
The answer x=13 or x=1
Step-by-step explanation:
Let's solve your equation step-by-step.
|x−7|=6
Solve Absolute Value.
|x−7|=6
We know eitherx−7=6orx−7=−6
x−7=6(Possibility 1)
x−7+7=6+7(Add 7 to both sides)
x=13
x−7=−6(Possibility 2)
x−7+7=−6+7(Add 7 to both sides)
x=1
Answer:
x=13 or x=1
To do this, either use a calculator or do write it out one paper:
45.67 x 32.58 = 1487.9286
Hope this helps!
