If f(x)=4x²+8x-9 find and simplify f(2+x)

4x² +24 x +23

Step-by-step explanation:

f(x) = 4x² +8x -9

f(2+x) = 4(2+x)² +8(2+x) -9

           = 4(2²+2.2x +x²) +16 +8x-9

            =  16+ 16x + 4x² +16+8x-9

            =23+16x+4x²+8x

             = 4x² +24x+23

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
