Answer: 16
<u>Explanation:</u>
x² - kx + 64
Since we are looking for a perfect square, then we need to take the square root of 64 to find the factors: √64 = 8
So, the factors are: (x - 8)(x - 8)
Foil (or distribute) to get: x² - 16x + 64 <em>The k-value is 16</em>
Fisrst one is just add the functions
(f+g)(x)=f(x)+g(x)=
8x^2+16x+6+x^3-3x^2-9=
(f+g)(x)=x^3+5x^2+16x-3
multiply
ok
f(x)g(x)=(x^3-4x+2)(x^2+2)
just multiply and expand yourself because I don't have my graphing calculator with me right now
