Math Problem Statement

F(x)= 2x²-3x+1 x=(a+2)

Solution

Given the function F(x)=2x23x+1F(x) = 2x^2 - 3x + 1, and the value of xx is substituted by (a+2)(a+2), the goal is to find F(a+2)F(a+2).

Step-by-Step Solution:

  1. Substitute x=a+2x = a+2 into the function F(x)F(x):

F(a+2)=2(a+2)23(a+2)+1F(a+2) = 2(a+2)^2 - 3(a+2) + 1

  1. Expand the square (a+2)2(a+2)^2:

(a+2)2=a2+4a+4(a+2)^2 = a^2 + 4a + 4

Now substitute this into the function:

F(a+2)=2(a2+4a+4)3(a+2)+1F(a+2) = 2(a^2 + 4a + 4) - 3(a+2) + 1

  1. Distribute the constants:

F(a+2)=2a2+8a+83a6+1F(a+2) = 2a^2 + 8a + 8 - 3a - 6 + 1

  1. Simplify the expression:

F(a+2)=2a2+(8a3a)+(86+1)F(a+2) = 2a^2 + (8a - 3a) + (8 - 6 + 1) F(a+2)=2a2+5a+3F(a+2) = 2a^2 + 5a + 3

Final Answer:

F(a+2)=2a2+5a+3F(a+2) = 2a^2 + 5a + 3
