Solve for x: 3ex + 2 = 74. Describe the process used to solve the equation and show each step.
1 answer:
The solution of the equation is x = 3.18
Step-by-step explanation:
The equation we have to solve is:
First of all, we subtract -2 on both sides of the equation:
Now we divide both sides of the equation by 3:
And now we apply the natural logarithm on both sides:
And using a calculator, we find

By factor theorem (v+5) is not a factor of the given polynomial f(v).
What does factor theorem mean?
When thoroughly factoring the polynomials, mathematicians apply the factor theorem. The polynomial's zeros and factors are connected by this theorem.
The factor theorem states that if a is any real number and f(x) is a polynomial of degree n 1 then (x-a) is a factor of f(x) if f(a)=0.
The factor theorem states that
f(x) has a factor (x-k) if and only if f(k) = 0
We are given the following information.
F(v) = v 4 + 16v 3 + 8v 2 - 725
We have to check whether (v+5) is a factor of given polynomial.
( v + 5 ) = ( v - ( - 5 )
f( -5 ) =
= - 1900
f(-5) ≠ 0
