Gerald is testing to see if a possible rational root is an actual rational root of a polynomial. He uses synthetic division to determine the value of the remainder. Which theorem is he using to test the value? a) Linear Factorization Theorem
b) The Factor Theorem
c) The Remainder Theorem
d) The Fundamental Theorem of Algebra

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

provide more details to solve it

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
