Answer:
x = 6.4
Step-by-step explanation:
Set up using proportion and cross multiply to solve:
8/10 = x/8
x = 6.4
U would factor by grouping and get x^2(x-2) + 3(x-2) and then get (x^2 +3) (x-2)
Answer:
A. No real solution
B. 5 and -1.5
C. 5.5
Step-by-step explanation:
The quadratic formula is:
, with a being the x² term, b being the x term, and c being the constant.
Let's solve for a.



We can't take the square root of a negative number, so A has no real solution.
Let's do B now.





So B has two solutions of 5 and -1.5.
Now to C!




So c has one solution: 5.5
Hope this helped (and I'm sorry I'm late!)
