Answer:
Below.
Step-by-step explanation:
Substitute x = 3 into each polynomial and see if the value of the polynomial is zero. If it is zero then x-3 is a factor.
Try number 1:
a(x) = x^3 - 2x^2 - 4x + 3
a(3) = 3^3 - 2(3)^2 - 4(3) + 3
= 27 - 2(9) - 12 + 3
= 27 - 18 - 12 + 3
= 9 - 18 - 9
= 27 - 27
= 0
So a(x) has (x-3) is a factor of a(x)
The other 3 polynomials are solved in the same way.
Answer:
The answer is B) 1/2(x+10)
Step-by-step explanation:
When any number or digit is on the outside of a set of parenthesis, you multiply it by what is inside. The sum of x and 10, which is x + 10, is multiplied by 1/2, which is one-half of the sum.
