HELP PLEASE QUICKLY!!!!
solmaris [256]
Hi again!

I think I already answered this question - right ?

Ok whatever - the answer and the steps are still in my head~

x^3 - 4x² + 2x + 10 = x² - 5x - 3
Again, same thing
x^3 - 4x² + 2x + 10 -x² + 5x + 3 = 0
Now factorize
(x + 1)(x² - 6x + 13) = 0
Set factor equal to 0
x + 1 = 0 or x² - 6x + 13 = 0
x = -1

The correct option is : B

A+ Guaranteed!

1) 3^b=9 root 3<br> 2) 3^c= 1/√3
Alex

Answer:

1) 5/2

2) c = - 1 /2

Step-by-step explanation:

1) 3^b = 9 root 3

Write in exponential form

write the expression in exponential form with the base of 3

3^b = 3 ^ 5/2

Since the bases are the same , set the exponents eqaul

b = 5/2

Therefore, your answer is 5/2

2) 3 ^ c = 1/√3

Write in exponential form

Write the expression in exponential form with the base of 3

3^c = 3 ^ -1/2

Since the bases are the same , set the exponents equal

c = - 1/2

Therefore, the answer is c = - 1/2
