Factor the expression over the complex numbers. x2+50

  x² + 50

= x² - (-50)

=            Side note:

= (x + 5i)(x - 5i)

Step-by-step explanation:

We are given that an expression

We have to find the factor of given expression over the complex numbers.

Quadratic formula  fro quadratic equation :

Using the formula

 and

Hence, the factor of is given by

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.
